I just got a Cannondale and have put about 1 good weekend of riding on it. I know it's not quite the same as a YFZ450, but still... I'd take it on the MX track before the Shee any day. The new technology it today's quads makes all the difference. It just feels more comfortable. Now on gravel roads or wide open areas, the Banshee still rules. I would say make the trade, but it really depends on the type of riding you do. If you just want to hit jumps from time to time, upgrade the suspension and hit it! I've hit jumps (well... one jump) on my Shee that my buddy on his 450r won't. It just takes more effort to hit a jump correctly on a Shee.
