Pulling spinners and bouncers is a great technique to look to add.
About what size bouncer to use…. there’s a couple of variables that will determine the needed weight.
Depth fished.
Trolling speed.
What you’re really looking to do is use a weight that is heavy enough to keep the angle of your line pretty close to vertical…. not quite vertical but don’t let your line angle kick out approaching 45′ like you would pulling 3-ways. The effectiveness in pulling bouncers is in keeping the weight dancing on that wire leg below the lead. If you get too much line out, bouncers fall over on their sides and drag…. resulting in way too many snags, a stirred up bottom, and of course, your spinner will basically run right in the dirt. Not good. So the answer is a little experimentation is in order. Some generalities here only but I find 1.5 ounces works well down to 15 feet, from 15′ – 20′ jump to 2 ounces and so on.
On the boards, Off-Shore makes the best boards in my opinion but I’ve also used Mr. Walleye boards as well as Yellow Birds and liked them OK. Off-Shore’s are the best, particularly when rigged with the Tattle Flags.
The best way to get a handle on the amount of line to run behind a board to achieve a pre-determined running depth is to purchase a book that supplies dive curves for a number of different crankbaits. That way you can simply look up the crank your using, the depth you want it to run, and simply play out that much line before hooking on your planer board. Precision Trolling is the book I would recommend.
Great questions. Hopefully some others will jump in to cover some of the points I’m sure I over-looked.
