I have not had any problems with flight with them. I ground some in the double beveled and some in the single bevel and that didn't make no difference either.
I shoot heavy hardwood arrows [oak,ash,walnut,hickory etc.] about 600-700 grains 3/8" diameter, 3 fletch in either 5" or 6", and both 1 degree offset and helical and they both shoot good. The other thing about my arrows is I cut them so that full draw brings the back of the head right back to my finger, then release.
I really dont believe that you'll have a planing problem.
