I think a lot is going to depend on how far you plan on shooting. If you are shooting within 30 yards or so, High Profile should be fine. I use Maxi-Fletches and 5 1/2 HP Sheild Cuts for hunting whitetail and such. Maxi fletch is almost a banana cut feather 5 3/4" long. But I don't plan on shooting past 20 yards or so. What you don't want if you are going to shoot long distances is for the arrow to slow down too fast which could cause the arrow to fly irraticle. The larger the fletch, the more chance of this happening.

As far as the choices in cuts, a lot will have to do with your personal likings of the fletch and the amount of noise you are willing to deal with. I believe Parabolic is the quietest. But I like the looks of banana and sheild cut better.
