sorry remi to correct you... VERY difficult to ride and jibe with the falcon. from the other side falcon is fast but very technical to have fun on it.
as remi said - for your skills Futura is MUCH better for you than iSonic, for handling on chops or jibing. but iSonic is closer to Futura, than falcon to iSonic.
you will learn to stay in planning after your jibe in 30% time on Futura compare to iSonic. i dont compare it with falcon.
