There are things you can do with handpouring that injectors can only dream about.
If you want a "cookie cutter" type of bait then injection is the way to go. If you want an "artform" type of bait then handpouring is the way to go.
It just depends on what you want; but believe me hand pouring will never be "shoved out". Another point is that handpouring doesn't mean flat side. I design all my baits and most are 360. I only own one type of aluminum mold and that is a top pour stick mold.
