*Mjolnir (85585 Mjolnir, apollo)
*Ptah (5011 Ptah, apollo)
*Orthos (2329 Orthos, apollo)
*Icarus (1566 Icarus, apollo)
I kinda like Mjolnir. it implies, among other things, something I'd carry with me all the time. On the other hand, that name might be better reserved for a general purpose UMPC. Ptah is cute, but might go bad quickly. Icarus may be a self-cursing name.
I kinda like Ixion. "Ick-see-on".
