I'm just trying to understand... You wanted to just shoot a single bait some times instead of the full mold? Bob must have thought you wanted a hand pour for some reason because very few of his molds are hand pour. You can still do laminates with that mold the old fashioned way: open the mold, pour one side, close the mold and pour the other half.
Personally I prefer side inject for sticks. In my mind, the salt,sand, whatever would tend to sink towards the tail in the vertical baits making them a tad tail heavy as opposed to the side inject where it would tend to sink towards the side of the bait evenly along the length of the bait. I could be all wet in that theory but in my mind it's possible.
