I can honestly say that I have never caught a shellcracker. I know there are supposed to be decent populations of them on Indian boundary but even there, I usually fish topwater for bass and bream and they are bottom feeders. I prefer to fish for the redbreast sunfish and bluegill in the rivers. The redbreast have a larger mouth and willingly take a smaller popper size 8 up to a size 4 . love the fish coloration when the water temps get in the 60s and they are spawning.
Plenty of public access to the LP on up in PF also in you don't mind fishing behind hotels. Also places along the road going up hwy 416 on the east fork of the LP.
