The two chokes will have different effects on the wad or cup. The compnchoke has slot ports as the Kicks has drilled ports. The comp n choke has the ability to vent the most gas following a shot because of the absence of surface area. The gas venting helps to slow the wad down as it passes the choke. Most new shotgun loads will seperate from the shot column at about 15 yards. The wad is designed to catch air and open like a parachute to help with seperation. I have posted before though, the best choke performance I have seen was from the H.S. Undertaker and a Benelli 3" #5 Winchester Supreme. The Undertaker is not ported and it stripped the wad wide open as it went out the tube. Undertakers are $20 but do not reduce recoil a bit. A major benefit from ported choke tubes is slower vented gases reduce kick.
