Of shallow, less than 10′ yes a bullet will be your ticket. Snakes through the weeds well. I have people setup with different weights to determine how boat shy fish are, and other things. 1/16oz, to 1/4oz.
Colors, again, vary until you find what they like. I find overall fish prefer what is on backside more so the front, ie silver, gold, chart etc. Beads, egh, whatever neutral colors.
Speed, 1-1.7. Pay attention to your inside turn and outside, if fish are hitting one way or other adjust accordingly to better present into the hotzone.
That depth better keep snell shorter, say less than 5′, 4′ is pretty good.
If not catching crap on spinners change it up. Throw a crank on, throw a spinner bait on, etc.
Good luck, report back.
