Got 2 fish this morning that really tested the Echo Carbon XL ESN 10' 3wt. Had the same experience with some of the fish last winter. Need more stick. Has anybody fished the 3 and 4 wt's of this rod, and is the 4wt noticeably more, especially down low, for larger fish. Since I figured I'd at least shop for a full frame ESN reel after this morning, I might as well look at a bit beefier rod to go with it.
