The 3D pro's are not exactly super light, but not terribly heavy either. Using 75/95s (340 deflection), vanes, arrows in the 28" plus length will be right around 400 grains w/ a 100 grain tip.

The Blackhawk carbons in my experience are horrid. There's a reason they are only about 30 bucks a dozen fletched (dealer cost). Their A/C/C knockoff (CAA's) are not too bad. Out of the 2 dozen I bought last year, most spin pretty straight (not all though), and weights are decent. Have not spine tested any recent models. The stock nocks are crap IMO. You will need to use a uni-bushing to keep the fibers from lifting up on the nock end. They also have a very noisy finish but if you are using fleece or teflon on your launchers they are fine. They also need to be cut slowly and carefully or the carbon will lift up. They do shoot well if those precautions are taken, and one can cut off the few that have straightness runout.

I have not used the ST AXIS on game, but I've been pounding the hell out of 6 of them now for about a month. So far I'm very impressed. More impressed with them than any other all carbon I've tried in recent years. Like the Blackhawk CAA's a few had some straightness runout, but they are not nearly as bad as the last couple dozen Beman ICSH and Goldtip XT's I've had. I've been able to cut off the bad parts and get some very straight arrows. Even without bushings they have been taking nock end hits with no problems so far (I've busted a handful of nocks and had to refletch 3 or 4 of them). I've left them out in this horrid cold we've had for days, pulled them out of the frozen targets w/ no insert problems, and they shoot fine. I'm not going to say they are the equal of an A/C/C for specs and accuracy, but so far they are pretty damn good.

I'll be trying some of the new Goldtip shafts too this year as well. Hopefully what I've been hearing under the radar about their improvements will prove true. But right now, IME the ST AXIS are hard to beat for an all-carbon.
