otoh, more bikes is more better! i personally don't like to ride my fully unless i need full suspension for long, fast descents, so in the mountains. i prefer a hardtail everywhere else. but if you just sold a hardtail. the questions is: "why buy another?" did you sell it to upgrade or try something new? or because HT is not your bag? if the latter, then i'm with Rob, the bigger wheels are nice and and different, but it won't blow your mind.

btw, the complete bike is a better deal only if you end up with a better bike. maybe you can find used wheels local forum or an ebay special?
