I don't know about whether the base would be narrower or not for equivalently sized in terms of area/hold, but if you look at the True Ames trailing edge just above the incut base it leans slightly forward, before sweeping backwards further up - this is a typical shape. The Griffin fin seems to go from approximately upright to sweeping back straight away. I don't know Greg's design reasoning, maybe he considers it excess material, I don't know. However, I see the Griffin fin as something that is raked from base to tip. The rake seems to help me maintain speed in a drawn out cutback - both frontside and backside - I do have to consciously hold the wide arc, but this sort of fin seems to allow me to do it better. Then when we want to pivot off the top the thin tip releases readily.Interesting. So narrower base and tip. I do like the drive I get with these. Some release, too, but only when I shift my weight to the front foot. Fin is pretty sticky when trying to pivot at the top of the wave.
i had issues with my first set of NVS. had to sand base to get them to fit.picked up a set up NVS (dan mann template) and the fins are nice but the bases are crazy different from fin to fin. one is super loose (thanfully it tightens enough with the grub screw), one fits normal, and two almost needed vaseline to get in there.
edit: I know it's not the boxes cause I swapped out with another quad set and they went in perfectly
You get what you pay fori had issues with my first set of NVS. had to sand base to get them to fit.
someone else on here had ill fitting set and they sent them back and got them replaced and new set didn't fit either if i recall? it's almost as if each set of fins isn't checked for proper fitment before it's tossed on the cargo ship from china...
So, I wonder who is handfoiling all their fins?I returned a set of needs fins cause they wouldn;t drop all the way into the box. tried it on different boards just to make sure. they refunded my money cause they said all of their fins they checked were like that
Yes. I think you are right about RTM fins. The NVS fins that most us are getting are g10. The foils seems good but the fitment and finish is definitely inferior to a Futures branded fin. The first batch I got was also very sharp. I like the g10 for twins/keels. They have nice thin foils while retaining stiffness. I get why GG prefers this material.I thought pretty much all RTM fins were made in China...
