I have a
2011 CrossCheck SS
2011 Salsa Vaya
2010 Specialized Roubaix Team Saxo carbon
2010 Fisher HiFi full susp 29er
If I were down to only one, it would be a toss up between the Vaya and the HiFi. I REALLY like both road and mountain biking. While the Vaya is a good adventure bike, I don't think it would replace a mountain bike....and the HiFi wouldn't replace a road bike. I guess I would probably keep the HiFi
