I don't know anything on the PAW rockers?
Nothing wrong with aluminum rockers, I have Crane, Harlan Sharp and T&D aluminum rockers on several engines with no problems. It seems higher valve spring pressure is tough on the rockers and valve train. A small hydraulic cam with Beehive springs is going to have fairly low pressures, so it is easier on what ever rock you use.

Hopefully someone with the PAW rockers will respond with their experience, but I'd use them.

I think all the factory rocker arms were the same? I hear the Mopar performance replacements were made of thicker steel?

If you want to idle nice at 700 rpm, I'd use a step smaller cam like the Comp 280HR-10 (PN: 23-711-9) maybe even have it ground on 112 LSA to reduce overlap? This is where I would be talking directly with the cam grinders to get their advice.
