Yes, you can run cranks during the summer months and catch walleye. We often run a bandit off our inline board with a 2oz sinker. Put out bandit 50ft then place a 2oz weight and rest of lead than put on board. That 2oz adds about 8ft of depth. One of our go to summer setup was a blue chrome bandit with 50/2oz /100 more for a total lead of 150 running at 2.5mph.That caught a lot of fish for us.But,as always, let the fish tell you what they want.
