I started using RAges last year...3 blade...i shot a deer last year with mine...and wooooo...this sucker tore a hole the size of a softball...crazy stuff...i used to use muzzy...nothing wrong with them...but these rages honestly shoot like field tips....
I'm with Liv2Draw. stop spending money on your bow until you know what he problem is for sure. I think Dubbya is on the money about your rest.Try the old arrows first and if they don't fly ,which they probably won't, center that rest. I shoot a trophy taker also and just last week I replaced the cord that lifts the launcher and started shooting terrible groups. The problem was that I did'nt have my launcher vertical enough at full draw Like berore I replaced the string. so everything was out of wack! It was a quick fix.
Well I forgot to come back here and say that I got all my problems worked out. AND i figured the main one out on my own! I had a limbsaver thing under my rest for silencing the darn thing and it was actually causing it to bounce back up and catch my fletching. Also I switched to 500 spine and man they shoot amazing! So now I have got these new arrows shooting like a dream. They shoot completely straight...absolutely no wobble whatsoever and the Muzzys are hitting the same spot as my field tips. So yay! Go me haha:D
