You won't find a more stand up guy than Nick boys.
BearGuy...that's been the biggest asset with Turbos that I've seen is the decreased wind drift.
I did a 3D last year and the last shot was a 51 yarder with a 35mph crosswind. I had 3 with conventional 4" hellical and the same shafts with Turbos and shot both. Held 18" off to get it in the 8 with the Feathers...6" off with the Turbos. EVERYONE was amazed...including me. I knew they helped but I didn't know they cut THAT much.
Now...if I was a guy that hunted Antelope or Mulies out west int he plains states where the average shot was 40+ and the wind always blows...guess what the best bet would be
