Aid Enchanting, Spirts of Man? Options

[TerraFirst!]

I'm referring to the optional rule on page 79 of Street Magic, which grant bonuses on enchanting tests per spirit type, but excludes spirits of man. I assume this was an oversight, though, it was never corrected in the Street Magic errata (or not the version I have). I propose granting bonuses to enchanting certain foci. I'd propose spell foci in general, though guardian spirits already grant a bonus to enchanting counterspelling foci. Still, this is three focus types, similar to a guardian spirits bonus to three focus types. Alternatively. which three types from the following list might be considered fair: Power, Masking, Centering, Spellcasting?
