I got my wife a new bow (Parker SideKick - nice little bow). She'll be shooting 40#, 27" draw (so ~28" arrows). I was planning on getting her some 3 blade Muzzys (75 gr. maybe 100 gr.). I talked with an archery shop and they said with the lower draw weight that a cut-on-contact blade (G5 Montec or NAP Hellraiser) would be better. What are your thought on: 1) 75 vs 100 grain; 2) Muzzys or c-on-c head; 3) NAP Hellraisers???? Thanks in advance.
