hard or soft copper line for a valley oil gallery bypass line?

I agree with everything except oil speed. I understand the number 1 main is feeding the entire drivers side. That's idiotic. But all the nonsense of the crossover and all the extra things done for it are a waste of time. There are better ways to feed the drivers side lifters than the crossover. And I'll say it again, oil speed is not a factor. It's there to get oil to the drivers side lifter bank.

All that other stuff is useless unless you are going over 7500. The biggest issues are the pickup side of the pump and the leaks.

BTW, a dry sump generally has one pressure side and 3 or 4 pick up sides. That's an example for Chrysler guys to look very hard at. We don't have nearly enough area of pick up tube for the pump.
Show me another way to feed the drivers side.
