I pour a few different soft plastics, I have a few hand pour molds and a two injections molds.
I do it for fun and my own use, and I swap with a brother-in-law in Michigan.
I use mostly Caney Creek stuff (

I really like natural colors with bright/neon tips/accents. I have some of the glow powder but I haven't poured anything since I got it.
The best plastisol I've used is the Caney Creek regular, it's pretty soft but still holds up. I've only tried a few others though.
It also repours better than the other brands I've tried and it has a neat action.
