Will the Hog 2nd stage service kit also fit the edge 2nd stage regs?

The Epic, EXP, and Escape octo all use the same 2nd stage kit as the Hogs. The Enduro and the egress integrated octo use different kits. And regs really should be rebuilt on an annual basis. Not wise to wait until they don't work, because learning of that failure may come at an inopportune time, like when you are trying to breath, underwater. Remember this is not just "gear" it is life support.
Most regs do not need rebuilt annually. An inspection and adjustment if needed is recommended. But even that is not necessary if the reg is not acting up. HOG and Edge regs have a two year recommended rebuild. Sooner if they see really heavy use and less than optimal care. But I have some that are working as well as they did when I got them three years ago. And they still don't need a rebuild. I've seen and heard of more problems than I care to think about because people did the every year thing with shops and techs who had less skill than they should have. Get an IP gauge, make a magnahelic with a ruler and your kitchen sink, and check your regs on a regular basis. When they start acting up get them taken care of.
The method I was shown in class does not even require a sink. The lever is adjusted to just about when it is about to drop from its maximum height, no more, and should not rattle when the 2nd stage is assembled. Violently inhaling at the full opening should initiate a freeflow, whereas normally inhaling, or violently inhaling at less than a full opening, shouldn't. Maybe I just had random luck, but the regulator doesn't freeflow while diving, and even breathes marginally better than the new ones I haven't serviced.
