iHop!!!! Oh man, their pancakes are pretty nifty!!! Mmmmm...And to be honest, I'm kind of caught inbetween if I want to keep riding a twin, or go back to directional.
In my opinion the effects of a small amount of setback just make your board more versatile...and for the most part don't mess with your freestyle progression...but again..just my opinion no more than say 15 setback..
Slightly set back directional twins are the bomb for a one board quiver..now if you can afford a few boards?? the equation changes.
