FCS2 vs Fusion

FCS2 vs Fusion - 02/12/19 12:38 AM

About to order a new boar. I keep telling myself I'll try FCS2 "on my next one" and keep ordering Fusion plugs because I already have tons of fins. This time around though, I could probably use a new set of fins anyways so...

FCS 2 will allow you to use all of your old 2 tab fins, so you have nothing to loose.

Go for it.

i believe fusion is a bit stronger

Both allow you to use 2 tab og FCS fins, although you have to buy a set of grub screws
if you want to use them on FCS2 boxes. FCS2 allow for a little bit more fore/aft adjustment,
if you think you want to play with placement more. If not, I think Fusions are simpler
and every bit as solid, if not moreso.
Obviously canít use FCS2 fins with fusions but donít see much drawback there.

I like how the fcs 2 plug is bigger . So when I use my old fins they sit flush-er

I don't see how the fusion tabs could be more "solid" than FCS2, which have longer point of connection, a leading edge that hooks in to a pin (like futures), and can also be screwed in (the same as fusion). I don't use the optional screws, and never had an FCS2 fin rip out (I have had the old fusions rip out their plug back in the day). Plus, I like being able to pop them in/out without a tool. Plenty of different templates/construction options, but backwards compatible too.
Other than cost, I don't see a downside to going FCS2.

i've had no problems with FCS2 on the 6 boards i've had them in.
I really like the accelerator fins , have a set of small and medium and use them almost exclusively.
sometimes the medium with the small in the back

What kinda boards/waves do you like the accelerators in? The board in question will be a 5'5 x 19.5 grovelor for thigh to waist high or so and flatter faced/sectiony beach break.

I've always liked Merricks in just about any board but might try something new.

use the mediums on my 5'10 x 18.5 x 2 3/8 26 liter shortboard, i'll put the small in the back for peaky beach breaks.
also use the mediums on my tomo evo.
also using them as quad fronts on my 5'4 x 20 1/4 x 2 3/8 groveller with the accelerator (same as performer as rear quads)

Smalls i use on my step up and on my 5'3 tomo vader and 5'4 tomo nano

if you want them for futures, they are the same templates as the gorilla grip fins

Something steep and tight, at least stomach-chest high. Outstanding pivot/response but zero drive/projection imho. I was ordering a board for similar, decided to try FCS2, this was very soon after they came out. Disappointing first few surfs. Bought grub screws, put in Merricks, board pushed back and went fast down the line as desired, Accelerators went fast on the erBB classifieds as desired.

I'd consider FCS2 just for resale purposes if at all applicable. Grub screws worked fine for me; people with FCS2 fins might be off the board if it has Fusions.

interesting analysis.
I'm wondering if you surf waves that are more lined up with open faces, the surf I get the most is quick and punchy.
My first board with FCS 2 I had the reactors and the performers, so I actually got the accelerators because they had considerably more drive than those two, albeit less than carver and AM's in a larger size, so i don't think they are low on drive generally, but maybe so compared to the Merricks. Like I said, the accerators are more inbetween in size, the smalls are closer to medium and the mediums are sort of a mid between medium and large. Compared to a large am fin i could see a huge difference in drive, but not hte mediums

Thanks for the responses fellas. Any experience with the carvers? They look similar enough to AMs but I think have more area so maybe too drivey. I do like drivey fins and donít care for anything too flicks but still. I can get the carvers on sale in FCS2.

Lined up, I dunno, but open-faced, or straight up flat-faced, yes. Most of the road trips to Central/South Florida where the surf is quicker, it's also very prone to being walled/closed, and swept fins race closeouts well for me.

They are pretty similar to AMs but all 3 fins are the same size. AMs have a smaller center fin.

The Super brand set seems identical to carvers but with a smaller center fin (L Carver sides and M center for size L, M Carver sides and S center for size M).

Iíve tried to adjust fins up and back with Fusions and there really isnít much wiggle room and itís hard to get the fins to stay put since you get a little indent on the tabs that the grub want to engage. Do you find FCS2 to be better on the adjustablity then when using 2 tab fins in terms of staying in place?

If its a standard FCS2 install with the jig cross hairs placed on the shapers dots, then the movement of twin tabs is entirely in the forward direction i.e no aft adjustment. The movement is quite a lot though - about 1 cm. So good for loosening up your board, but not so good if you want to stiffen up the turning/drive.

If you are doing the install yourself with the intention of only using twin tabs, you can of course place the shapers dot slightly more rearward than your target position to give you that aft adjustment, but this would rule out putting in FCS II non adjustable fins on that position.

I know exactly what you mean about a fin only wanting to sit in one place in the fusion box despite the adjustment room provided. For fine forward adjustment of twin tabs in FCS2 similar problem. The screw will want to sit in the indent. For more substantial movement like 1/4" then it will go past the indent and not have that problem. Both situations could be fixed by elongating the dent with a Dremel tool or something, but that's a bit of trouble if you don't have such a tool.


FCS 2 is a much better box than fusion. The plastic fin tab housing is encapsulated in a polyurethane foam body which doesn't need wiping with acetone and should provide a more forgiving transition to the softer blank foam. The flange is perforated to give a good bond with the glass lam. I bought the install jig and kit (comes complete with the special router bit) and it is about $100 cheaper than the Future install kit. This was my main reason for choosing that over Future for self builds. I did the first install with the help of industry pro Josh Dowling who is a Gearbox fan. It was his first experience with FCS II and his comment at the end of the process was "easiest install ever".

I have both but have a preference for Futures. Not a big deal but I find more futures templates that I like.
Some of the old fusion fins are money, like VS Stilettos.

I know what you mean about the normal grub screw indentation causing the fin to
revert to the center spot. IMO FCS2 boxes definitely give you more adjustability,
but it can be a slight PITA to wedge normal FCS fins down into the boxes in the spot
you want forward of normal without fíing up anything. Being careful though, much more
range before screwing them in. Iíd prefer Fusions with longer slots for more
adjustability, personally.
