What do you plan on using the choke tube for? Ducks, Turkeys, Coyotes ETC? You can drop a small fortune on a Choke only to be unsatisfied with it and it's hard to get a honest opinion because Different Guns will shoot Different...I bought a $60+ Kicks Choke from Bearice but it still wouldn't out-shoot my $20 Primos tight Wad IN MY GUN!!! So I sold it...Kind of a trial and Error process and unless you get it from Walmart I doubt you can return a Used Choke on the Fact that it didn't meet your expectations.
i aint to sure bout wad wizard. but ill live an die by a full kicks high flyer. best choke ive shot hands down. from what ive read about wad wizard i wouldnt shoot em. if you look on their website they got some pics of patterns from different shells, but they aint to impressive in my book.
