Anyone running a 904 behind a 340?

Yes, I know all that. Joe Average want a silky smooth, slippy, sloppy shift, thus not using the rear band in 1st (Drive).
Racers want a robust trans, thus applying the rear band in 1st.
What's your actual point?
You can get Full manual VB's that don't apply the rear band in 1st, but they are not the safest to use, and you can lose your toes..
My point, I have no point, you asked why buy a better sprag, and I have tried to explain the reason for it. Because in some situations, poorly prepped track, it is still possible to hurt the sprag. I understand how the release of the brake works by releasing the front clutch, even that varies by manufacturer. Some release much faster than others. The griner brake and it’s derivatives are very popular because of the speed of there release. I have met many racers of the 904 who switched to a power glide because they claim they could not keep the roller clutch from breaking. For some applications there is a need for a stronger roller clutch. That’s all I was trying to say.
