I think those are pretty good choices. When selecting your Mystic Potion, I'd try to find one with the most upper pattern you can though. Some almost look like typical BEL, while some still have very small alienheads or leftover dots that fade out at the bottom and a strong dorsal stripe.That way the Mojave and Mystic that makes them up goes easy on pattern a bit.

Like as an example this little guy would be a better line for this specific purpose


vs this guy who is gorgeous but might make it more difficult


Special probably messes with it the least of the BEL complex, but it's also the hardest to ID and might not be the best choice for that reason.
