Soft on a roll is K copper, if memory serves.
Me, I'd want the rigid stuff with the thicker wall.

Personally, I went with the heavier copper just for the extra life it
might give
me. City of Seattle recommended copper.
That is the type M, right?
I'm not sure which type is which, but you'll want the 3/4" soft variety
for this application. It comes on a roll.
