Check the trail on the fork, it really can make or break a bike IMHO. Most of the newer bikes appear to have straighter forks with less trail. I much prefer the older more relaxed geometry that was prevalent in the mid 70's sport bikes. I have had a couple of long haul tour bikes that rode like a train on rails, they weren't quick handleing but very comfortable for long all day riding. Too many of today's bikes are aimed at the Lance wannabees and the tri riders which is a whole different style and type of riding. You can have a long wheel base with a fairly short trail, head tube and seat tube angle also play a part in it. Relaxed angles slow the steering a bit but give increased overal comfort.
