I realized a couple of things about the rigging on the Side D, firstly, the multiplication of turns on the line and increased friction because of it seem to keep everything from moving around, which is obviously important but if you ever did need to change the i) position of D ii) length of hip riser then a little bit a pulling and pushing can facilitate both things. Sliding rings back allows riser to lengthen, and vice versa.Your Valiant is looking very sweet, and I really like your idea of terminating the side dees with a splice... Gonna work on that one myself.
As someone who spent most of his career in saddles that do not have any bungee/elastic/webbing running from the waistbelt to the back of the leg-pads I almost alway remove it from any saddle which has it ... This includes the TreeMo, MCRS and the Valiant. I have found that all this connection seems to do for me is pull my leg-pads up, causing pinching...No thanks..
"The friction coefficient on the lower D's has to be the lightest on the market, webbing can not move as slick as rope and because of this the Valiant feels fast and intuitive when moving around in the canopy." This is one of the things that separates Matt's designs for the rest of the pack, and until you have experienced it you wont understand what you are missing. Matt's saddles flow like water out of a faucet.
