I have tried the Berkley Havoc Grass Pig and I don't mind it.
The tale action in the water is not as aggressive as some of my other swimbaits but the pike and walleye went for quite well the trip that I tried it.
The tale also flutters on the fall, were as some swimbaits don't.
I was rigging it on a jig with a minnow shaped head and longer hook shank.
Adding a stinger hook near the tail area also helped me in the hook ups on those light bitters.
