I haven't been using my jerkbaits as much as I'd like to but they can be effective almost all year round. Fall and early Spring tend to be the best for most but again, winter and summer can be awesome!
Charturse shad is by far my favorite color and can be used on almost any lake and I've caught fish on it in gin clear water along with muddy Spring Lake last year.
I generally prefer the regular Pointer 100s but will use the deep diver, 78 and 128s along with the Staysee. The 78 deep diver has been killer on Clear Lake during this time of year for the last few years.
Biggest I have so far is only 6lbs but have many fish in the 4-5 lb range (most of those in tournaments!).
