If you tip with shrimp and are fishing anywhere near structure just be aware that you are going to get alot more then just flounder. When I tip my jigs I use something a little tougher so I don't have to retip every time I cast. Flounder belly, snag a pin fish and use it the same way you would use flounder belly, and squid cut into strips. It takes a little more to knock that off the hook then shrimp does.
