To answer that 70-bucks question, pheros aren’t of much use when stranded on a desert island all by your lonesome, but I get your point. 
Here are my picks..
MX135 - there are PLENTY of threads about this, especially recently.
EoW - you already know what this stuff gets you into, apparently.
Instant Honesty x2 (to go!) - wouldn’t be without it.
I’m tempted to say… P103 (also to go) - happy, sunshiny loveliness!
