Since I've been in the 3rd grade when my dad got a pontoon, I've pulled BB's. That's all we did until I learned the Lindy rig in college. In the 90's my friends turned me on to pulling plugs (they weren't cranks then). With the super braided lines coming out and a boat that was perfect, I quickly learned how to catch fish on plugs. Since I fish alone quite often, I find it a lot easier to fish two lines pulling cranks. Always put fish in the boat and keep enough to eat fresh walleye most of the soft water year. I sometimes use BB's alone, but on the rod I have in the holder I try to put one of those floating little plug like things. They work and don't snag as much. For me anyway, I catch way more fish when my BB is on the bottom. I have a lot more snags with them than cranks, a lot more. I'm not sure I'd put a bunch of rods out and put them in holders with BB's. I'd have to know the area very well and know its not snaggy. Planner boards and BB's would be a big hassle if the rod with the board kept snagging. Plus when pulling BB's it really helps to have the rod in hand to set the hook, unlike cranks where the hook themselves. I've missed a lot of bites on rods in rod holders using BB's.
