Dennis,

I' ve fooled with them over the years and have a dozen (1/2 of 3490s & 1/2 of 3600s) currently.

1) They are a bit heavier on avg, than A/C/Cs (not neccessarilya bad thing)

2) They have a really crappy nock (no unibushing

3) They NEED a unibushing because of the design..they are very suceptible to nock end cracks unless you use one.

4) They are not always within tolerance for straightness (most are pretty good however, much better than the average all-carbon,but they don' t approach A/C/C levels in " the real world' )

5) They have an unpolished finish that is extremely noisy across a rest

6) They are a bit more finicky when you cut them and the carbon will lift/crack/separate if you do not cut & rotate them very slowly

7) Inserts are wider to accomdate broadhead ferrules, but are also heavier and not as high quality as the Easton inserts.

Good arrow overall. By the time you spend 20 bucks though to put unibushings and G-nocks in them, IME/IMO you might as well just buy A/C/Cs. :shrug:
