I am wanting to shoot a few laminate colors, and was wondering if purchasing the dual injector was the way to go. I have several different molds I would want to use, from Do-It, BassTackle, and Angling AI. I just wasn't sure if this would work with all the molds I have? Also I have a 4 oz Do-It injector, should I just buy another one and the kit, or just buy the whole works together? Thanks for any help on this, just trying to determine if this will work like I want.
