I had that same idea recently but I've since changed my mind. Two reasons:

1) Braided line does not have the abrasion resistance that mono of the same diameter doees so if your plugs are working down and around sharp rocks, then you could be in trouble.

2) You want stretch when a fish grabs a plug. Whaaaat? Yes, you do. There has to be some give to the rod and the line when plugging so the fish can grab the plug and turn with it. I use softer plugging sticks and straight mono now and I can honestly say that I stick more takedowns than ever before. I see too many guys with super tight drags (another plugging no no) and stiff ass rods that usually help with the empty takedowns. Trust me on this one as I am a "plug monkey" and I have learned what not to do the hard way. Peace
