Nice trip!! Those caves are pretty cool. I went last year, I was a bit surprised that they were so open with no signs or warnings. There were some pretty big holes you could fall in.
I got a few saturday, nothing great. Biggest one was about 3 pounds but most were pretty small. Got a lot of perch and sunfish trolling on sunday, along with one decent size walleye.
Mine's still pretty messy but I started to label all the spots in my tackle box. Helps to keep lures organized by depth. I need to get some small boxes for some of the smaller stuff.
I like the single blades better than the duals. Like uglyfish said I don't think the colour matters much. But all mine are bright colours, like yellow or bright green. I've had pretty good luck with them but mainly use Jitterbugs for topwater.
