warlord,
It depends on how long ago you got the MTX-2 pro spec, at one point they were including Jaco Foams, and later on they had Mugen Fast foams in them.
Ducati,
We are still waiting for response from Serpent on the 705
Novaracer,
We might have something later on next week. We are also working on carrying other brands of V1R Hop-ups.
Sorry for the delay in response guys.
