Im not sure if you would get any gains from adding the cp reg though?
Probably not, both the Hyper2&3 are great performing regulators.
However, I'd easily swap to a CP
if I wanted a different feel for the marker in question.
Personally I prefer that the macroline fitting comes out of the bottom like on the CP and not out of the side as featured on the Hyper3 regulator.
If it had the smaller 'Hyper 3' thread, yes!
CP makes them in the Hyper3 threading, just making it clear for the threadstarter
