I have had good luck with the ones from Brambleberry.com - but remember that not all EO's will stick no matter who they are from. Citrus scents (especially lemon and orange) tend not to stick no matter who makes them. Their lime sticks well as does spearmint, listea, lemongrass, peppermint, tea tree, eucylaptus, basil (smells like Thai basil - a bit of licorice to it), and rosemarry. Those are the ones that I've tried in CP.
I also like their tangerine, orange, lemon, grapefruit for other things (such as scrubs, shower gels, and foaming hand and body wash) that aren't CP - haven't tried them in MP yet - but will one of these days.
Hope that helps.
