I have only had the pleasue of going after bass once, but it was a blast. Montana isn't exactly prime bass country.
I have a standing invite at Billy Deans place to hit his bass ponds which I need to take him up on at some point. I guess he has some monsters in there. For trout, I use various mepps, Panther martin, Thomas cyclone and blue fox. I have been getting some killer deals on big lots of lures and spinners on ebay over the last week. I should be stocked for years to come!
