Well, With the 320, I think you would be fine if you put a 5-7 color on it. I have all from a 3-12. When summer hits, I use 5-12. With 5 picking me up a lot of bows and browns. You can always let out a little extra backing to get that extra couple of feet. I do not have any 320's set up for LC, but i do have a copper set up on a 320. And thats a 100 Copper. Works pretty good. Let us know what ya come up with.
