not sure the validity of claims on the silicone mod that sorbo isn't consistent. How much more consistent than +/-5 can you get? Sorbo has been used on dsg builds going up to that magical 90rps and there are no issues.

With a harder material comes more shock transferred to the front of the gearbox. Sorbothane was researched and chosen for it's shock absorption properties. it also takes all of 1 minute to install and does the job fine. I'm not sure why'd this messy alternative is any more appealing when you're talking the tiniest of gains for proportionally a lot more work.

Not to disregard his claims, as you could stick any pad in there that's good at retaining shape and absorbing the shock load from the piston, there's a few different types of material out there that do it, but for 5 bucks and a bit of CA glue and 1 minute, what's the point of spending 24+hours to get the silicone set properly for very little gain?

I've seen guns with airseal at +/-3fps and that's ridiculous. When it's down to that it's more than likely the variances of the BB not being perfectly spherical.

Go with an ASR fet, I'm not confident with a pico being able to handle these big builds. I've installed several ssr2 and a couple have melted down.
