I have an '08 and love it. Never noticed any issues with the handling or anything else. With that said, what the others have said, ride all of them before making a decision.
Biggest difference from 08 - 09 was the frame, swing arm, lrgr rear tire, re-designed rear fender, small cosmetics. For the right price - either will do so definitely try to test ride both years & see whic you prefer. Good luck!
