bead size for harnesses

hey guys just wondering whats the best size of beads work best for harnesses?? Also whats the most common sizes of blades?

depends on the body of water i am fishing.4mm 5mm 6mm for beads./2-6 for blades,green bay i use #5 and #6 blades,w/5mm and 6mm beads.#2-#4 blades for smaller inland lakes. everyone is different but that is what i start out with, then let the fish tell me what they want.#5 split shot 30′ back behind board to 2oz bottom bouncers. average speed 1 mph

Sunday we were catching a few fish using the larger 5/6 blades. We had a few out with 2/3 blades and they were getting popped. After switching them all to 2/3 size blades they were all poppin’. Beads were 4mm and 5mm. They may need to be adjusted as well so it is good to have some rigs tied with all sizes and colors to be able to adjust easily.
