Id recommend X2 colorant just for your fluorescent colors. Other colors i would get spike it. These are great colorants and much better for mixing custom colors. Not sure why but i dont see many crappie guys mixing their own colors any more. One drop of X2 is too strong without cutting it down for tweaking colors.

If you ever plan on doing laminates i would just bite the bullet and get the twinjector from basstackle now. You can break it down and use the injectors individually for single colors also!
