1. In the never ending quest for the ultimate in long range archery accuracy, all other things being equal, which is more critical, arrow straightness or uniformity of weight?

It would seem to me that varying weights would produce vertical “stringing” on the target (related to time-of-flight/velocity variations) while shafts with straightness issues (say .006” total indicated run out) would produce more rounded groupings.

2. On any given bow draw weight/draw length, will shafts of a slightly stiffer spine produce better groups than shafts of a slightly weaker spine or will the opposite be true?

Of course, answers submitted will require apt justification for given opinions!
