Why a Reverse Valve Body?

I run a mrvb and have for some 25 years.
I know how to treat it, and i know how you can blow up a sprag. and i don't do it.

However, I can't control all the thing that cause a sprag to break. drive shaft, axle or rear end breakage. but i'm knowledgeable enough, to know, that if that ever happened.........the transmission would come apart for inspection, before i ran it again.
You can't beat a no rev band 1-2 shift(mrvb). You may get that 1-2 shift with a rev band timing perfect.......and then it will ONLY shift AS WELL as a mrvb.
Argue all you want! it's a true statement.............
