Being of the large persuasion, I have taken a great interest in the Hawk & Tornado seats
95kg is the max nude wt for Tornado for a zero-zero capability. From 95-106 kg it is a zero-30kt seat. There are plenty of graphs around the safety equipment empire that show the limitations.
If you are on the tall side, sitting thigh length can be a problem in the Hawk.
I'm 6' 3" with 34" inside leg and I only had 5mm knee clearance. It sure made sure that i strapped in and sat carefully!
Hope this helps.
Unfortunately as you advance in years, the weight settles differently and you have to be careful
