I often troll to find fish then stop and cast or jig. Usually works good for walleye and if I find a pocket then seems like there is usually a big Norther near by.

Last year we had a real good lake trout trip and caught most of them trolling. It was the first week of June. Seems like they usually hit when we'd stop or turn or slow up for some reason. A few times I reeled in the slack, ready to start paddling again and found a LT was on. If memory serves when we went back to jig and cast the same spot where one was just caught, it was not too productive. Maybe I haven't figured out how to work the jig yet just right  for LT. I did catch a few on a jig by casting and bumping the bottom on the retrieve.
