Another thing I have experemented with from cattle(scence I work with them every day) is spinal tissue/brains, spinal coard, spleen,ect...... This is something that works best in ponds because brains are harder to keep on a hook in current. The scent also fills up a pond better. Spinal cord stays on a hook good no matter what because of its tough outer membrain. This is also a good bass bait. If you have access to it(a slaughter hous) give it a try. Oh ya, Ask the processor if they have chicken guts too. Those work realy good.
