I am just now starting to experiment with swim baits on my home lake, it is a clear deep lake, and it is stocked with around 200,000 trout a year. I think that the smallmouth are feeding on these trout a lot, so I am interested to see how the swimbait will fair. But I can not imagine putting down my grub. The grub has always been a hot bait on the Laurel Lake in the spring time. I have a lot of sucess on the 3" bass pro shops spring grub, wish they still made the 4", but the 3 does good too.
It all comes down to confidence, and I have a lot of confidence in my grub, but I'm willing to give the swimbaits a chance.
