I'm actually thinking after another 150 mile day that I do want to upgrade the seat after all, though not for height. Breaking in did help noticeably, but not enough to make it totally comfortable to ride for a couple of hours straight. Very curious to hear if the gel saddle helps with this, or if I should just go all the way with the Russell. (Note that in my case, I can't hold it against the GT, I've ended up going with a custom on every street bike I've owned - guess I have a delicate rear end.
