Hakko,

do whatever you are comfortable with.....i went (in like 3-4 months) from a .40 high wing trainer to a 25% edge540t. i never flew the edge on a buddybox either...i have alos flown a 40% carden extra and edge, and i was co mfortable...i know some 3rd year flyers that wouldnt touch the 25 let alone the 40....do whatever you want and are comfortable with...
