I've seen Adam Drake, back in his TLR days, in an instructional on YouTube about how to do the foam compensation in the 8ight shocks. I've also heard of Tessman using a bladder with the vented cap: that makes the most sense to me as far as bladder shocks goes.

I know this thread is resurrected from the dead, but today it appears nearly every major team driver is running emulsion almost every race. That's in 1/10 and 1/8 scale! I only got into racing a few years ago, but I've only run emulsion. The kit setup for my 8ight-E 4.0 is bladder, but all the posted setups are emulsion so I went with emulsion too.
