Recoils are bomber, the flex feels good to me too, stiff enough for jumps/speed, but it doesn't feel like your fighting a 2X4 when your jibbin or land backseat. You get used to weight really fast. I had nthe toothpick nine lifes before these, so if I can handle the change anyone can.
2bi4 is lightyears ahead of 4bi9, whens the last you saw someone build a house using 4bi9s? -jfletcher
