>>To some degree, I think a lot of folks subscribe to the "two barrels, two different chokes" theory
You know, I used to subscribe to that theory when I used O/U's but found that for the most part, I get by just fine with an IC choke. However, I sometimes carry a Lt. Mod. choke for those rare occasions where IC might not be the best choice. I think perhaps our shots aren't as long here in NH as compared to the wide open spaces of Kansas. :-)
