coolpond, our ponds are about the same size and I also lean toward lmb, but I was persuaded by a pondbosser George Glazner(I hope George forgives me for misspelling last name), George talked me into adding some HSB to my lmb pond and I am happy I did it. they will put up a bigger fight than the lmb will and are a pleasure when u set the hook. Maybe some research here might open up a spot In your pond for the HSB.
