I'll admit -- I've got more bike than engine right now When I decided to get into this sport I had the money to get a nice Felt w/HED Jet 6/Disc wheels. Fortunately I do most of the passing (as I'm about 2/3 on the swim) and the last weekend I would've been in the top 10 bike had it not been for a flat.
This year is all about experience and trying to figure these things out -- next year's about getting faster, didn't want to buy 2 bikes and the TT bike is so much nicer to ride.
