hey I got this bike that has the 440-4229's on it and the progressive site says that they are 12in shocks.... How much difference in handling is it to have the 12 vs 13's??? Is it worth shopping for the 13's or trying to make a trade w/ someone??? I am 6'1 200lbs... they ride great but the bike sit's much lower and I can't corner very hard

tell me your opinions on the difference and if it is worth it to change the shocks....
thanks,
