I liked the biolos fins a lot. Felt like I could push the board really hard and still maintain complete control.
I had a set and I have no idea what happened to them.

Most of my sets are on the larger end.

Not surprisingly different boards require different fins.

I weight around 160.

My old Lost Min Driver worked best as a thruster with the Mayhem fins. With smaller fins it lacked drive. The Baby Buggy I had seemed to go best with Accelerators.

My Hypto was pretty stiff with bigger, and/or rakier fins. Works great with K2.1/WCT template or the EA template or Kinetic Phase 3s (all on the small side). I tried the Craig Anderson Blackstix which seems like they should work, it got really stiff even in big surf. Despite Craig Anderson weighting 140 pounds dripping wet, his fins are pretty large.

Basically I don't think you can make one rule for every board. Tail width and rocker seem to play a pretty big part in things. If I had to generalize smaller fins for smaller tail and less rocker.

For me AM templates don't work in anything.

I wouldn't take pro's or semi-pro surfers equipment as a measurement, anyone not in the same talent category or training regime will likely never compare to those guys and girls. Featherweights on tour are skinny but powerful, they have to.

Ride what works for you and not what everyone else is on.

I get a lot of amusement surfing before and after a big snowboarding weekend. Amazing how much the extra leg muscles help.

I really ought to do some dead lifts and squats.

Like what? I think there are some Pancho fins that are pretty big.
I think he was alluding to the fact there are no XL fins, on L fins.

So you can only move up in size if you're midweight or smaller.

He's making a good point.

Aside from the wide tail thing where you actually need a bigger fin... I think this is more about learning to ride large fins and the level of skill the rider has to do a deep bottom turn.

Too me, bigger fins feel tracky in real waves and can be downright scary in cooking hollow waves where you're trying for the barrel. Per GG's posts I would imagine fin placements are adjusted for this.

I also think you can see an obvious difference between how tight Lakey's surfing looks vs how loose Filipe's looks. And considering Filipe has 25 lbs on Lakey, and they're both riding large fins...

I always thought it was kinda funny that someone is going to use the same size fin on their 5'11" that I use on my 6'6"

Yep, partially alluding to that, but also partially asking for real.

I know there are several people here who use fins outside of the templates available on FCS or Futures websites, and I'm wondering if any larger surfers who can either confirm or deny that there's validity to what the smaller guys who like L size fins are feeling.

It seems kind of insane that I'd ride the same size fins as someone like Noel Salas who'd fit in my pocket. Then again, I like large AMs, Fannings, and Accelerators, so I'm mostly going to the larger, driver, hold-ier end of the large fin spectrum and I think the only of those templates that smaller guys are using with regularity is the AM. Maybe there'd be benefit to me getting on an XL AM if such a thing existed :shrug:

He's riding like 5-7's so a bit less rail line than us bigger guys which I think is a factor but it is kind of interesting that there isn't many larger than AM2 thruster sets.
