I run a QAD HDX, but I’ve seen guys run a whisker biscuit and trim out the sections that the vanes run through so there’s less resistance, but still arrow containment.
Was a strong believer in QAD till I screwed on a hemske. WAY easier in my book. In a big fan of limb drivers for hunting now. QAD is really finicky. Good rest but you need 2 people to tune I feel.
