the Slump Buster is a good one for bass and trout. I mostly use them for trout, but pick up plenty of smallies on them.
Slump Buster, if you didnt know, has a very specific other meaning... but that's not for this forum.
Trout fishing is such a specialized area though... I mean to really target trout, especially wild ones, you're needing to have quite a wide range of patterns.
Seems that for bass, of any kind, you can get away with tieing very few patterns anyway... Of course, I'm no bass expert.
When I used to cast lures, I can count one hand the different types of plugs I would ever use for LMB and SMB. Now that I'm really getting into targeting bass on the long rod, I'm sticking to the same theory which is, if its an easy meal, a bass is usually hard wired to kill it.
I mean, I rarely ever used anything besides a floating silver Rapala for bass.
