yeah, i'll try 3-4" rh feathers first as an experiment. i guess if i'm shooting a perfectly tuned bow with a perfect release, arrow flight should be just as good as with 3-5" rh feathers.
i guess i'll see how perfect my tune and release are.
when i went to a finger release and feathers, i started with my arrows fletched 3-5" rh. Since i've had such great success with this config, i haven't tried any other fletching set-up. i was trying to think of a comparable set-up (in terms of arrow flight and stability) using shorter feathers. it does make sense that if i HAVE to use a four feather set-up that i might as well forego the 3" feather for a 4" feather. (thanks for that advice.)
I'm afraid I can't answer your questions about rate of spin. It stands to reason that a 3" feather fletch will spin slower than a 5", assuming identical offset/helical settings, due to less surface area, but that's just 'thinking out loud' instead of knowing it for a fact.
yeah, that's kind of what i was thinking also...
again, thanks for the help!
oh, one last thing...
never trade off control and accuracy for speed
i wouldn't dream of it.
