Time cap 20 minutes
Scale to 95/65 if you want a shot at finishing and for most of us a much better workout.
If you have a 185/135 thruster you are welcome to try it out, but know when to say when. Hurting yourself for an RX makes absolutely no sense. 55 thrusters at that weight is doable for some, 55 wall walks is doable for some if they were separate. Putting them together is entirely different thing.
Just be careful
