I've dinked around with mine and made some improvements. There's no doubt the thing could benefit from some silencing, but part of that is also becoming more familiar with it which makes you less noisy handling it.
I added stealth strips around the horizontal bar, side members, and the angle bars. As far as the pins, I've added heat shrink to the retaining clip part and, most importantly, ditched the steel wire that held the pins to the stand. I found those to be bothersome because they made extra noise and slid all over the place. I replaced them with d-loop material and drilled an inconsequential hole in the front side of side bar to hold the back pin and tied the other to the fwd part of the platform.
I've got a 3' foot cable OTW. I think I'll probably use that more than the 4' that came with it.
