All good advice so far. My favorite and most important advice when asked about bikes, frame material, etc. is fit. Don't go by anybody's reccomendations to buy a bike if it doesn't feel right. No matter how smoking hot the deal is, if it doesn't fit right you won't like riding it and you won't ride it and then you've just wasted your money. It could be that both of these bikes fit you just fine and both feel good, that's wuold be cool, just don't buy one that you think is nicer or is a better deal if the other feels better. Fit, fit, and fit!!! Have fun!
