Mike, unless you are fishing strictly for keeper/big bites, you may be missing out on a lot of action. A jig that big just isn't going to get you the number of bites that a Ned rig or shaky head will.
And before anyone slaps down the small fish card, I introduced a guide buddy at Broken Bow to it a little over a year ago. Last spring, he or clients caught two 10-pounders and a 9 on it.
