Weight mold

[BearLakeFishGuy]

I'm honestly curious as to why anyone would want 8lb weights instead of heavier ones? Electric downriggers have no problem with weights up to 18 lbs! Hand crank downriggers don't really seem to matter since I can't tell the difference between a 8lb or 12lb when cranking them up. The heavier weights track straight down whereas the lighter weights swing back behind the boat. I've tried all different shapes and sizes and found the pancake style is the best tracking, less resistance, etc. Could someone explain the reason why you use the lighter weights?

Oh, I only have a mold for 12lb weights. They actually come in about 11.7lbs when weighed on a scale.
