The way I read the thread, the RGM kickstarter was not an option for the original poster. Maybe I missed something.
I have RGM kickstarters on a couple of my Commandos.
They have their place, but IMHO are a little over-rated.
They don't work with some rear sets.
They don't have a spring or detent to retain the swivel part in the retracted position.
The ones I have were machined so the swivel did not stop at 90 degrees. I had to do some tig brazing to fix this.
After a few years of kicking, the pivot hole/bolt fit is getting sloppy cause there isn't enough metal around the holes to keep them from going egg-shaped.
The leverage is nice, but the stroke can be excessive. Sometimes when I jump hard on them, at the bottom of the stroke my knee begins to invert. That never happens on a stock kickstarter.
