GT XT Hunters. Trim them evenly from both ends and use the pin nock bushing system and cull through the dozen. This is what I did for hunting season last year, because the pros were in low supply and impossible to find. The entire dozen ended up within 3-4 grains with I think 9 of them being within 1 grains. They all spun very well, but I would make sure to cut from both ends to make this happen. You should be able to get them for about $65 per dozen + a few bucks for the pin nock system (well worth the $$$).
