i just don't get it.
i shoot every kinda shaft material out there, from woodies to carbons, in all manner of stickbows from hill to moab. they all work just fine, once i figured put what works and what doesn't work, for me.
it never ceases to amaze me all the hubbub over certain arrow shaft materials being 'difficult to tune'. i heard that a long time ago about carbons. i bought a buncha different spine shafts. didn't take long to realize the incredibly wide dynamic spine range of graphite, and in short order i found some shafts that bare tested quite nicely. but i hadda to the legwork and in some cases go against some of the carbon arrow dogma rhetoric one finds too often.
i'm no genius or rocket scientist by a long shot, and it didn't take much to figure out what arrows work best for me, and what don't.
but it does take time and effort to figure it all out, and no one can find the correct answers but me, 'cause i'm the one shooting the arrows outta my bows, not you or them.
the key is in getting a 'test kit' of sorts, and spending the time to figure out what works best for your bow(s) and you. do this bare shaft, you don't even hafta know how to fletch (though you ALL should learn!).
