All good info, and thank you for it. Although I did cut them down, it was not all that much. I had a GT3555 that was 28" long with straight full length feathers, field tip or BH it flies very well. I cut them down to match it @ 28", and even though I have 5" and 4" RW shield and parabolics on them they both fly exactly the same, they weigh 450gr and 440gr depending on which BH I use. I was surprised that the 4" para's handled both broad heads.
Now as soon as my ring finger gets better, I'll be able to shoot with more confidence and less strain.
Thanks again
Oh and P.S. this is all for a hog/deer hunt in Texas next week.
