I have used a few types but I keep coming back to calhoun plastic. I prefer the soft formula for more action in the baits. supersoft is too soft. med aint bad. saltwater formula is to stiff for small baits. just rock the jug back and forth really good and you will be fine. when you cook it up to working temp let it sit to the side first and all air bubbles will come to the top and you can skim them off. reheat and your ready to go
