Yes, two versions, one with LBA and the one without that Paul at TA recommended, as I explained in my first post. The question is whether that was not the best choice, in retrospect.

Regardless, I'm moving on from this topic. Thanks - Brad

EDIT: Sometime since I bought my valve body, TA replaced the older 17675 FMVB w/ LBA and 17680 FMVB w/o LBA (what I have now) with new "Xtreme Action" versions. Short of calling up Paul at Turbo Action and hoping I'd understand what he'd tell me, I really don't know what the differences are.
