I've been pretty serious with getting away from flake, myself, here lately. Using Pearls and Hilites to add that 2nd color, instead of adding flake. This way my remelts look better than they may with flake because alot of the flake will curl on subsequent reheats, more-so with Saltwater Baits. With just Colorant and Pearl and/or Hilite, there's no flake to curl (or bleed) so the reheat looks better and is usually more true to the original color, again and again.
I'm getting into Hand Pouring OP molds, so no flake is a plus here as well, because the plastic has to be a little hotter for OP molds (in general terms) so it flows better...more heat = more curling/bleeding of the flake, if flake is there.
I've actually thought about selling most of my flake because most of it has been replaced by Pearls and Hilites...
