I havent shot any of those but Iam useing the carter solution 3 and also the stanislawski. The solution 3 is a little on the pricey side. If you haven't shot one and don't know if you are going to like it ,I would try to find a used cheaper model and try it out. My favorite training aid is a 4 finger stanislawski set with a long travel and a clicker. It has tought me patience in my shot. Good luck, you are on your way to a whole new standard of shooting.
