I was using a 3/8oz bullet weight with a 5" delta money reap. It is a custom reap that if you want to see ask me at the next tournie. Its similar to a black and red reap but with brown in it. I dont like using weight to much heavier because once it falls through the water it sinks pretty fast. The 3/8oz is hard to get through the stuff for sure. I would say on average about 1 in every 3 flips I made actually fell through and into water, you have to be patient fishing this way something I am not much of unless I believe that this is where the fish are going to be.
