Thanks a lot Ian!
My weight is 85 kg and most of the sailing in 6.5 conditions is 95% blasting, I never do any new school freestyle, and wave conditions is a pretty far drive away.
2 straps in the rear seems to fit this sailing better.
Maybe I should just buy a 33 cm fin and se how it works? Maybe that is a right choice even with my 6.5 because of my weight?
Is the gator more bottom end oriented? I see that gator 7.0 uses 430 sdm(I dont have a 460 for a ncx 7.0)
