I bought one of these molds last spring. Prior to buying it, I don't think I had tried any plastic swimbaits. I really like this bait for pike in the spring, however I didn't get much chance to try it out on bass over the summer.
From the side of making lures, you can make some pretty awesome colored baits with it and the belly is really easy to hand pour. I only pour these baits (or any for that matter) in medium plastic.
