I took one of mine apart and redid the insulators. I used orings from Ody kits. I took the bottom piece of silicone off and put one of the orings on the center pin. Then from the topside I pushed the top silicone down inside the put two more of the orings and put it back together. Now it's really solid, I can rotate the post if I want but it stays where I put it. I can adjust the center pin on my Poldiac and line up the air hole without pushing the post up. Trying to do it yesterday it shorted and collapsed my spring, that's what got me off my rear end to find a solution. Really a bad design flaw, but I'm loving the atty now. Here is the kit I'm talking about:
Odysseus Replacement O-ring Set
I had to get into two of the kits because there are only two of the smallest per kit. After I got it all together I came across my GGTS oring kits and they have even smaller ones. They probably would have worked better on the top side, I really had to force those in. Even though they are out of stock, the GG wiki site will list the specs on the orings.
