At What Water Temp do you go from jiggin to casting for walleye?

we ran our harnesses on the bottom bouncers 6 ft of leader off of a 2 oz bottom bouncer trolled any where from 40 to a 100 ft back at 1.3-1.7 mph, either flat lined or off the boards. and for the reef runners 80 to 135 ft back (800 series) off my big boards that was pretty much the program for all 5 boats we had with us. one other thing that might sound a little strange we used toilet bowl floats also. heres how we used them. you go buy 2 floats paint them orange and then drill a 1/8 in hole across the stem where they screw on to the rod in the toilet bowl, and then insert a large snap swivel in to the threaded stem hole and put a small cotter pin thru the hole you drilled in the stem after you get the swivel on attach a snap ring clip to the swivel. then you let out your bottom bouncer to your desired distance back and clip the float on to the line and let it back as far as you want. we will run 2 and stagger them about 30-40 feet apart. the object of the float is to keep your line centered behind the boat and it also acts like a bobber of sorts. we caught about half of our fish on the harnesses using this set up.
