Rich,
So I am assuming you would stay away from the A1. The one I was looking at today is not even on their website yet, but it is like the middle of the road for the A1's. The Sirrus I was thinking about is actually the low end, strictly because of budget and I can pick it up for about $100 less than the Trek 7500FX.
The A1 was really a nice bike though, however I don't know how it would be on a 50-60 run.
Thanks,
PF
