If you do intend to hire a guide then I suggest

Joe and Steve are two of the best on Winni or anywhere for that matter. The spawn will be in process so numbers shouldnt be a problem but the wind can be a big problem on this lake. That would be an advantage to a guided trip as they know where to go depending on the direction and severity of the wind. Its also a great way to perhaps learn some new techniques to take home with you. If you decide to go it alone and can say what area you intend to explore, I would be happy to help if I can as I spend way too much time bass fishing there...lol
