I'm sure this has been beat to the ground, but I'm looking for some advice.
I currently have two 5 wts that I mainly use for trout fishing on spring creeks. I've also used both on a river in my area to catch smallmouth and whatever else is around (even got a small walleye last summer), just fishing small streamers/jigs. It worked pretty well, but even getting in a 1-2 lb smallmouth was quite a task, especially with current.
I'd like to go out on an area lake this year, where I wouldn't necessarily be targeting anything in particular, but want to be prepared in case I get a large fish on (northern, musky). I typically just use marabou/flash streamers from no bigger than size 8 hooks.
What weight rod would be good for this? I've been told 8, but that may be too heavy for smallmouth, but a 6 or 7 might be too light in case a large northern comes around. This is more to make sure I get the fish in without wearing it out too much.
