I get my Goldtips from Morava Archery out of Rushvile, NE. Tom weighs and sorts the Goldtips and then includes a little sheet when he sends them out to indicate the weight. Then when I need to order more I'll let him know the weight of the last ones and he usually can send me some within a grain or so of the others. The other thing and he hasn't had to do this often but he'll cut them in such a way as to get them as straight as possible. He also makes them up with the goldtip g-nock adaptor and the g nocks and that makes for a real nice finished arrow. If you have someone like Tom making up your arrows I think you can have complete confidence in the Goldtips, they are a real durable shaft.
