We use nothing but Calhoun here, all handpours. When you go to injection, I think you'll find you will have less problems as Calhoun (uncoloured, clear) does turn that ugly tan colour after a few hours in the pot doing handpours. Injection is so fast, I don't think you'll have those problems. No one is cheaper than Calhoun and Al is right about you get what you pay for. In your case though, I dont think it will make a difference in the finished product.
