Best patterning choke tubes for the money - Carlson's Choke Tubes Remington Sporting Clays 20 Gauge Choke Tube

I have sets of these Carlson extended sporting clays choke tubes for 3 of my shotguns. I have a 4 tube, 20 gauge Remchoke set (Improved Cylinder, Light Modified, Modified, Improved Modified) that I use in 20 gauge 11-87 Premier, and 870 Wingmaster Special Field shotguns. I have a 4 tube, 20 gauge Browning Invector set that I use in my Citori Superlight. And I have a 2 tube 12 gauge Remchoke set for my 11-87 Premier and my 870 Wingmaster Special Field. I have found they produce much more even and filled out patterns than the factory flush mount choke tubes. When I replaced the flush mount choke tubes with these Carlson extended sporting clays choke tubes, my sporting clays scores increased by another 10 broken clays. I am ordering 2 more for my 12 gauge so I will also have a 4 tube set for that gauge.
