Have to agree with the Versatility+ opinions 100%. To do the big miles though I bought a corbin seat with backrest (love the backrest), progressive rear front and back suspension and a tall screen. Now I can ride (I'm 6'1" and 200 lbs) all day without too many probs at all. Mind you, I'm probably a bit soft and sometimes use a airhawk after 800K's.
As far as overheating or reliability, I haven't had a single issue.
All in all, my Shiela is perfect for what I want - everything
