Well, just bought a new rod

Yup. If you own a #5 it makes no sense at all to get a #4 or a #6. The rod you have could handle any of the three line weights just fine, probably - If there was a need to.

Rod length probably makes more of a difference. I'm getting the #3 for use on small streams, but in truth, I could probably just sling my #5 line and reel on a 7-foot #5 rod and notice little if any handicap.
