I know this is not what you’re after, but I build my stump arrows to match the hunting arrow, but leave them as dedicated stumpers. They have heavier brass inserts and heavier steel adapters to make the judos match weight. The reasons for dedicated arrows are that I still stump a little in hunting season, I use these to shoot a few shots into a stump or dirt right before heading into the woods and because I don’t want to subject my hunting arrows to the same abuse unless I’m taking a shot at animal. Best, dwc
