the mold is a pain to make and make it work for hand pour guys, as most of the top piece is contoured. more work means more price about double of what a regualr swim bait mold would run.
I got one and played with a few variations of it the problem is if it doesnt have the arc on the top just right it spins like a SOB. making that arc on the top piece is were the cost comes into play.
you also have to make them so they pour with little to know trimming. Guys dont like to buy molds were you have to trim in 5 different spots, nor do I blame them.
They cannot be poured through the nose with the same thickness of the org bait, that has to be opened up big time so it will pour all the way to the tail. if the web thickness is double( which would be an absolute min to pour if your lucky) the bait swims wierd, any bigger and it doesnt swim and does weird stuff and spins.
no all that being said, make one with POP (Plaster ) or silicon and they will pour fine through the nose. I know silicon does and I was told by one of my customers that plaster does as well but I have not seen the plaster one.
Silicon tends to flow the plastic through smaller openings rather easy alot easier than Alum. I don't know if its due to the slipperyness the smoothness or the heat it holds but RTV does pour alot easier through small openings as compared to Alum.
I got them in alum, I am not 100% happy with them, I am definatly not happy with the price that I need to sell them at. Once I can get them under 200 bucks then I will be happy.
