What size hooks are typically used on flipping jigs say 1/4-1/2 oz? 5ot?

It really depends on the mold/manufacturer, but 1/4oz = 3/0, 3/8oz = 4/0 and 1/2oz = 5/0. This is typically what I see and have used. What particular mold are you working with?

do it molds, thanks for the breakdown of weight vs hook size

Nothing smaller than a 5/0 on ¼ oz & up

Nothing smaller than a 5/0 on ¼ oz & up

I couldnt agree more

Depends on the hook maker as sizes are not consistant for all manufacturers but 4/0 and 5/0 are what I use the most.
