IMN23D, doing things that way would match the spine within a dozen arrows pretty well I suppose. Problem is, some classes have rules that all arrows must be identical in all respects. Same brand, same size, same fletching, same points, same length. So, with the arrows all trimmed to different lengths to get spine matched, you' d wind up with arrows that aren' t technically legal under the rules. If you' re in the top 3, someone will file a protest on your equipment, even if the arrows are just slightly different lengths.

Not to mention that someone like me that shoots barebow and uses a hard gap system for targets, you NEED all your arrows exactly the same length or you' d be using a different gap for each arrow.

Chief, I can' t make a call right now on what arrows are ' best' . Like I said, I need to mike the diameters of all those arrows and make sure they are round before I make any conclusions. Just going by the results I' ve gotten so far, the PSE CarbonForce arrows have the best spine consistency within each shaft. Shaft to shaft consistency isn' t all that great, but if you could sort thru a batch, it wouldn' t be any big deal to spine match a dozen. Then you' d have to weight match ' em too.

A grain scale is going to be my next investment.

I don' t want to get anybody upset but, I swear, the further I dig into these carbon arrows, the less I' m impressed by their consistency. And I wasn' t that impressed to begin with.
