Anyone running a 904 behind a 340?

I think this is where the confusion started;
if the band is on during transbrake, after the launch, and depending on the valve body design, if the slicks were to hook, slip, and rehook while still in first gear, you would be on the sprag without the band on to help.
First your saying the band is on, then your saying it's not on, it's a little confusing.
That's why I made the comment about the non band apply VB's.
