Dial-A-Jets work okay for what you're talking about.
They will never meter as accurately as a sized orifice, but they make life easy for an altitude hopper.
I've got several sets of unopened Dial-A-Jets that will work on the HP series. Make me an offer.

I am currently running some 'adjust a jets' in my Demons from Percy. They have really made it a lot easier to dial things in... I believe I have the original set for the Demons. Percy is hell of a nice guy, his parts have made my life lots easier.
