I don't shoot the XT's as they can be bought almost anywhere, and at a fairly reasonable price. For both hunting and tournaments (what kind of tournaments) I shoot the UL 22 Pro series. Although they are a 300 spine I can get them to tune decently anywhere from 48# to 72# at 27" long.

For 3D I set them up with 80 grain Nibbs and 2-4" feathers. I hate screw-in points. For hunting I use the typical insert and screw-in broadheads with Duravane 4" LP vanes or feathers. No need to spend the extra money fro Pro series if you don't want to. If you cut about 1 1/2" from the nock end and finish by cutting from the point end you should end up with a pretty straight shaft. Something around .002".

Then there is the regular Ultralite series which come in the common 500, 400,and 300 spine and accept regular inserts and nocks, supplied by GT. At 27" and using 80gr Nibbs I can get the weight of the 500's down to 267 grains, which fits right into my 53# 3D setup. I don't use these for hunting, but could with inserts.

Understand there is a tradeoff with any shaft. You can go thick walled and heavy for better penetration or thin walled and fast. The thin walled arrows are more fragile and can break easier, but I just consider it part of the cost of shooting. And being fairly accomplished at it a dozen arrows last me 5 years or more. I don't group shoot anymore and rarely do I miss a target shooting 3D so arrows last for years. Usually I end up getting something newer and the old ones go into my arrow bucket.
