I've got a mage-face I'm playing (shaman, Dragonslayer Mentor), my very first character in a proper Shadowrun game. I've decided to invest in 1 essence worth of bioware/geneware (no cyber) once I get the money, mostly to get R3 tailored pheromones. Even standard, that would leave .4 leftover essence, but I'll be going for at least alphaware. Since thinking about future options helps keep my interest between sessions, I'm looking for advice on what to take. I have my full 6 essence, and a few pieces of highly-recommended bioware from Prototype Transhuman (sleep regulator, platelet factories, mnemonic enhancer).
I've been poring over the available bioware/geneware, but still not sure what to get. Neuro-retention amp, hyperthymesia, and PuSHed all look useful for mental things, and synthacardium looks nice for shoring up weak athletic ability, but I'm open to all suggestions. I like how the first three synergize with mnemonic enhancer at least. Cost isn't much of an object as this is long-term planning.
TL;DR: For a mage getting tailored pheromones and thus .4-.7 "open" essence, what further bioware/genemods would you recommend?
