I weigh in at an unenviable 105kg and bent the rails of my 2013 Flite with hollow Ti rails, so maybe something with solid Ti rails (if you can find anything)?
Filling in the hole in the middle of hollow rails hardly adds any strength. Rail bendage is a matter of torque, so it requires both a force and a distance. If you find a post which puts the clamp near the middle of the rails rather than at one extreme or the other, the chance of bendage is much reduced.
