RE: Is my new set up sufficient for Elk?
NYSHunter - Another bit of advice ? Go with big vanes or like I did, use big 5 1/2" feathers. I stuck with 3 RW helical fletch, 5.5" feathers and used all 3 white. I marked the cock fletch with a sharpie or used the nocks with clicks on 'em. You'll be a bit slower in arrow speed, but you'll have more stable flight, forgiveness and that'll lead to a bit mroe accuracy IMO.
Another thing if you haven't done it - bare shaft tune your arrows to get the BEST flying arrow, then add feathers and watch some pretty arrow flight !
good luck
