Which Expansion Chamber?

[F4_paintballer]

Which expansion chamber should I buy for my F4? Some of which I like are the Benchmark, ACI, and 32 Degrees. I saw that the ACI and 32 Degrees X-Chambers got good reviews but i haven't heard much about the Benchmark.

you should get the ACI 6-stage xpansion chamber.....I have heard a lot of good things about it and it seems to work really well.....

I have a 32 degrees six stage and it's worked wonders for me.
