yeaa but still the dm8 hyper 3 is the nice one i dont like the look of the hyper 3 on the pm'sThey won't as the Hyper 3 has a different thread to the Hyper 2, I think I read somewhere that there is a Hyper 4 which is a Hyper 3 with "standard" regualtor threads, why DYE didn't stick with normal threads I don't know.
Lacey the SLG and PM8 also have the same reg, and someone on the nation will have "modded" one so much it now fails to work so a hyper 3 is available seperate, if you want to be that picky!
