I'm not a scatter gun expert but I've always been told that the best choke for slugs is IC. If you look at Remingtons sight for example, their combo shotguns come with a 20" smoothbore fixed IC barrel for slugs, or of course the fully rifled barrel.
I have shot a lot of slugs even out to 200 yards.Brenneke old style with the fiber wad screwed to the slug and have found the Mod choke to be ideal. Also works well with buckshot and birdshot so I believe it to be the best choice by way of an all around compromise.
