Unter, I can't really deny or confirm your experiences. This will be my first lengthy experience with a low trail bike, a big experiment. The previous owner felt it was a little touchy, and the builder attributed that to the raised bars, abobu 4 cm above saddle. I'll be riding it with bars level to 1 cm below, not 4 cm above. Different handling? I'll never find out.
I do have my Trek 610 set up with a low trail fork, and I do not find it squirelly at all with 700x28s, it's very nice. Same for the old UO-8 (about 65 to 70 mm rake), with fat enough tires (27 x 1 1/4 are much better than 21 mm tubulars on that one).
