So what I'm gathering is this: buy the .001's and the .006's at least once in your life to see if there is any difference. if one can honestly shoot the .001's better and notice a difference in their accuracy than go with the .001's. if a person can't tell a bit of difference, cheaper is better.
Exactly! I would also suggest (from my experiences with ICS carbons) to pay particular attention to spine. I've had more troubles grouping broadheads due to spine problems over anything else. In my opinion the spine ratings on ICS carbon arrows are too generalized. For example GoldTip 5575's , most archers would assume that if their shooting a poundage anywhere in between 50 - 75lbs that the GT 5575 would be the arrow of choice. I've been shooting between 62lbs - 67lbs for the last seven years with five different bows and the 5575's have been too weak in the spine with all five setups.
Same with the Beman ICS hunters , I've had no troubles with the 340's , but if I went by the charts (which I did to begin with) they tell me to use the 400's.
Just something to keep in mind.
Just wanted to add that I also cut my arrows from both ends and I make sure both ends are perfectly smooth and level , which I consider probably the most important steps in building an arrow.
