G'day Dave!
For your long draw length, I'd recommend the stiffest of the GoldTip Traditionals. They come in 75/95s, 55/75s, and 35/55s, I think. The numbers are just a really rough guide to match them with bow poundage, but your long draw will require the 75/95s. Get them cut to the length you want.
Then, keep your favourite Zwickey broadheads, and matching field points, and put a 125 grain steel adaptor in (they align really well). Do whatever you do to tune using the insert that comes with the shaft.
If you find that the arrow is too stiff, you can screw-in these little brass weights on the back-end of the insert (you'd have to heat it up to take it out if you've glued it in). These little weights come in 5 grains, 20 grains, and 50 grains, I think.
If your arrow is not stiff enough, then the easiest way to correct that might be to swap the 125 grain steel adaptor for a 100 grain one, or a 75 grain one. Then there are the aluminium ones which weigh 42 or 35 grains.
The people at Black Widow are really big on fine-tuning carbon shafts, especially with the GoldTip system. There may be other places to get this stuff, though. At present, 3Rivers doesn't have GoldTip shafts or the screw-in internal weights for these (they have other systems, but I don't know anything about them). But, at Black Widow, they do have a GoldTip test kit available, where you get a few different shafts and weights to fiddle around with, before deciding on what you want.
Two DVDs where Ken Beck of Black Widow demonstrates carbon arrow tuning with what I've mentioned are the "Black Widow Owner's Manual Companion" DVD and the "Masters of the Barebow II" DVD.
I hope this helps,
Ben
