I went air dog 2, the kit is very well put together goes in easy works excellent. You set the pressure you want and it has no trouble holding it there. Most guys say as long as you have a fuel cross over and an airdog 2 theres no reason for a reg return set up.
what's a fuel crossover

I think my preference would be an orifice in the rear head fittings , rather than an added regulator
there would be a problem getting the regulator on the filter and the added regulator to play nice together

An orifice would flow a little fuel back to the return, providing some cooling, while adding a path for any air that was trapped in the fuel rail, due to leaking injectors
Say a 0.020 or 0.030 size orifice in the return
