Amen Last Dollar. A number of years ago I was having a shooting lesson in the UK, my tutor was Mickey Rouse, a number of times world champion Helice or ZZ (dont know what you chaps in the States call it) We had done a few layouts and came to the high tower (120 feet or 40 yds) and I said to Mickey I was a bit concerned as the gun was choked I/C, I/C. he took the gun off me and commenced to bust 8 out of 10 clays from the tower FROM THE HIP !!! He handed me the gun back and said "Mike, with modern cartridges and under 90% of all game shooting conditions, choke is largely immaterial as long as you have I/C and a decent pattern"
