I have had time to look at equipment and a 4oz dual injector will work very well with the small 1-1.5in stinger shad sizes. Making 6 colors max would cover all my needs. If anyone has an idea of the Plastic softness of a BGBS that would be great to know. I don't like the softness of those so I don't want to buy or formulate plastic that soft. Another question, I can't see buying a single injector then later buying a dual unit. Seems it would be prudent to just buy the dual unit and only use one side as needed. Do y'all agree with that logic?
