rowin, you bring up a good point about the conflicting computers in dual setups, that's why i mentioned the FITECH dual setup having the computer in the one TB, with the second TB controlled by the first as a sort of slave unit. i didn't see anything like that offered with the Sniper setups, but i may have missed it.
i'm trying to learn all i can before plunking down a bunch of bucks, by asking lots of dumb questions, and scouring out any and all experience with this stuff first.
i will go back and visit the dual TB setup[s] to see what CFM each TB is capable of.
the crossram has been on the shelf for 30yrs or so.
