Is there a particular reason you're opposed to the poly?

I have not searched for the rubber ones in some time but did buy the poly variety for the last 221 I had out.

If it's noise level reduction thing, I personally cannot tell a significant difference between which has rubber and which has poly purely from noise level.

I can however tell which ones have 85-140W and which have 80-90W for gear lube.

I do like the poly because it doesn't allow the case to walk around nearly as much and I have a hard time trusting quality of reproduction rubber products. Some of it doesn't seem to last very long.

If I come across some rubber ones, I'll chime in with source.
