I also have to change out my hardware. the damn bolts are constantly getting loose! My only gripe with the stand!
Not sure on this, but I would definately look into it if I were you.
Footrest are a must. huge comfort increase!
I picked these up before I even received my stand. They will go on first. You can never go wrong taking the pressure off the back of your legs.
I would not modify the straps used between both halves. I am 6 ft and have mine at the very ends of the buckle while climbing up and down.
Are you using as a Sit and Climb, or as hand climber?
