which is better and why forward or reverse pattern mvb

I have an A&A reverse pattern valve body and the reason for that is the band is applied in first and the sprag is not used so there is no chance of the sprag failing and causing the transmission to over rev and explode on the next run and yes high gear is all the way back and you can't get to neutral but it has not been a problem and the transmission does have braking when you let off the gas. I think there is an explanation of this on A&As website or just call Rick Allison about it at A&A and he will be happy to explan it for you.
