Is there a service out there that allows you to try a lot of different chokes without buying them? If not it would be a cool idea to have a "choke rental" where you could pick a few chokes to compare, pay a few bucks to try each one and the cost of shipping, like paint samples, before spending the money to buy several to compare. Then you could determine which works best for your gun. I have read over and over on this forum about people spending fortunes on multiple chokes and only recouping half their money back selling the used chokes. Just a thought.
