You can drill a 1mm- 1,5mm hole in the cap, to get rid of most of the rebound from the air trapped behind the bldder.
Ghetto-er shock holder: Take the cap off your brake cleaner can and drill four holes with a body reamer.
The #60 drill sized hole I suggested is 1.04mm in diameter. It will remove all of the rebound not just most of it.

For TCS racing it is. However, if you recall, I went round and round with Eric who is one of the tech guys in the thread. He finally relented and said that it would be okay if we plugged the hole. Therefor, you can use the hole to bleed out the air during the build and plug it with some cyano after.
The concern is that using a hole like this will alter the shock action. Yes it will if you drill a hole much larger than the #60 sized hole I suggested. However to assuage their concerns, just put a drop of cyano over the hole. It's not needed after the air trapped between the bladder and the cap is relieved.
