Almost any good broadhead will fly true. You can check your arrows / heads on a spinner to make sure they're not wobbling, but if you're getting an issue with planing - it's probably an issue with your bow tune/setup or your form.
With that said - there are some heads that are more forgiving of a tune or a form issue, especially at longer ranges. The most forgiving fixed blade I've tried so far is the Wac 'Em, followed by the Solid, followed by Shuttle-T (Not all C-O-C heads though)
VPAs are one of the strongest designed heads I've seen, easy to sharpen, but they've been a little less forgiving for me. Going to re-tune my entire setup this year and see if I can get them flying well.
