Jeff, sorry....been a bit busy at work and just hit or miss on the board here.
Not much experience with the Heritage, lots with the Terminator Hunter. I would think the 45/60 would work just about perfect for you at your #/length, may have to bump up the point wt a bit but not sure as all my experience is with shorter yet heavier draws and the 60/75's. Sad thing is, they are taking them out of production. I guess they were just simply too good, too tough and they need to eliminate them from production to sell more.
I do know the heritage is a very tough shaft as well, though not quite the TH, but quite a few folks who have trouble breaking them at your poundage level.
I don't have problems with the nocks popping out unless I'm using the weight tube inserts. Then, I just use a drop of CA glue on both the insert tube and then on the nock and they stay put. I have had the nock pop out without weight tubes, but it was usually in a shaft that had been hammered pretty hard. It was very, very seldom without the weight tubes.
As for nocks, I prefer the Easton nocks, because I can open or close them at will to fit whatever string I prefer. I don't sand them, just tweak the ears on the nock when necessary. I've never had a nock fail this way, and get exactly the fit I want. But, you can do the same with the CE nocks, just be careful, their plastic is not quite as flexible.
Currently, I've got a few TH's that I'm saving, but am switching my #1 Morrison over to the Carbon Tech Rhino 60/85. Heavier than the TH's (now getting around 650 in my finished arrow instead of 600 with TH's), almost as tough (I don't think anyone will ever make a shaft that tough again) and actually getting as good as if not better flight than with the TH's. I buy them from Ken Thomas here on Tradgang, highly recommend both him and the Carbon Tech Rhinos.
