if you live in the san diego area or can get to it, they have the 4" ospreys at boss bait & tackle. i was there last week looking for swimbaits and they have a big selection, especially on ospreys but they were out of all of them ecxept some 7" ones in colors that i thought weren't even worth making(for super clear water like most of the sd lakes). but who knows, those color patterns could be very effective because a bass has never seen them before. one of them i remember seeing was totally clear. maybe these colors were made for murky lakes.
instead i got a 7" stocker trout. it looks sick in the water!!!

i don't know who else has the 4" though

good luck
