When swapping out trebles what size do you change them to, for danny's? for needles? for red fins? for pencils? for darters? Do you go bigger in front, smaller in back? single hook on the back? 4x, 6x?

Some plugs you can't change size(weight) as it'll wreck the action.I simple swap out for better quality hooks like VMCs.Needles that come with a rear treble are about the only plugs that I change to a single.And some dannys.

Factory stuff like bombers simply get a better quality hook of same size and style.

I almost forgot.A lot of tins like Kastmasters can have both style and size changed and they still work well.I like BIG single hooks on my tins.
