Can't comment on the Nitrons or the Slick Tricks, I can only compare the Sonics and the Muzzy's. it is the truth about the Sonics, they fly just as accurate as my feild points. but I have to use blazer vanes. if I use 3 1/2 inch vanes with the Muzzy,s the arrow flight is vey inconsitant and fly low (9inches and to the left at 40yards) with the same 3 1/2 inch vanes and Sonics its a little better only 6 inches low and to the left. But if i use the blazers (not the minies) and the Muzzy its just 4 inches low. and the blazers and the Sonics is the hook up: dead nuts. 1 1/2 groupings at 40yards. using st axis 340's 100grain arrows, Hoyt Striker II at70#, Cobra sight, and a Wisker Biscuit. I was thinking of using the Soncis for turkey, havent killed anything with them yet (frist year to try them). doesn"t sound good for deer. maybe just use the Muzzy's and adjust the sight.:darkbeer:
