I have fished dozens of different a.c style baits. When they first came out the big thing was making your own. I have a collection of about 15 different ones that friends have given me over the years. As far as the ac plug every one i ever fished swam a little different. The z plug I have fished quite a few times also. greg silks the owner of the company make 2 different plugs. His original one is a one piece plug. This plug has thinned out a little bit over the years. He also makes his 2 piece model that is like the ac but has bucktail at the end instead of a worm king. Both baits I have watched land a large amount of ten + bass.
