I would have to agree with Rob about rod wt, fish size, and fighting a fish. I understand where phaaker is coming from when talking about stressing a fish. I feel that much of landing a fish quickly is in the fisherman's ability to do so regardless of rod size. An experienced or inexperienced angler will land a large fish faster on a heavier rod, though it may lengthen the learning curve on how to quickly land a fish if it were to be caught on lighter gear. I grew up using a light power spin rod.Then, when I finally could afford to do so, I bought an ultralight. Most of the larger fish I was catching in my youth were carp and bowfin. I guess I learned at an early age how to land a big fish with small gear, but I do not recall ever having to revive a black bass if it was kept in the water or instantly returned after a quick photo shot, unless it was badly hooked. That's just my take on things. That being said. I think it is probably easier to learn to cast with a heavier fly rod such as a 7 wt. I must say, I was a slow learner when it came to casting a fly rod.
