frankly, all that stuff is quite confusing to me. And I'm a numbers person. You have to ride them. Go to the LBS and play! Sit on them, get them fitted, go for a ride. You will soon learn just exactly what you like and dislike. Then you can give more weight to the geometry once you have an idea of what works for you.

All my opinion of course. Once I had my bike, I could use the geometry to compare it to others to see if I think I'd like that bike too. (I've been doing this with my drooling over Bianchi bikes). I'd still need to ride it, though. But it helps me figure out which size will fit best (it's interesting that the top tube lengths are different even on bikes that are the same "size").

Good luck. I tried out several bikes, and it kept coming back to how good I felt on the one I bought. Go play at the LBS.
