Re-read my post numb nuts!!!
I re-read, and still you are saying that a board with normal shape vs those with a different shaped nose/tail, that the normal shape has a longer effective edge, which is the area between the contact points. THat is not correct, most boards that are for example blunted on the tips have a longer effective edge. It also depends on the shape as well, a cambered deck is going to be have a longer effective edge than one that is rocker.
But then again you have 2k posts vs my 7, so you must know more
And the NS hype on this forum is unreal.
