I've ridden the mediums as a thruster in my new stepup and they felt great but slid out when pushing hard through turns. Large's aren't as spicy but I'd rather go for hold on that kind of board.
Ridden the mediums with 3.75 quad rear on my 6'1 round and it felt great. Need to try as thruster on that board next.
I really like neutral templates and that one feels good.
So I swapped out my KC fins for medium 2 juans and I actually like the kc mo betta. Mayeb it was the conditions but the KC's felt more crisp and snappy. The trailing edge is definitely sharper/more refined.
I know you all probably don't care. I'm just babbling and making noise.
