My ears were ringing, lol - Cagey's reasons for wide frets are sound, and additionally, bending just doesn't really happen on a bass beyond some vibrato. That said, I personally went with 6105s, since to get wider widths with SS frets you'd need to go fairly tall, and depending on how heavy your touch is you can definitely alter the pitch a fair bit; it's a little easier to get truer pitches with shorter frets. I'm not sure if you're using the mute (sort of a sponge/foam deal) with the bridge cover, but since you're going vintage I'd consider the 6105s or even 6230s.
My personal choice would be the 6105s (that's what I had installed on the Jaguar), but if you're a heavier left hand player or want to keep with the vintage aesthetic the 6230s might be for you, plus since they're SS you won't need to worry about having much play to account for fretwear. Also, you can do a lot of cool 4 string 7th chords, and with the shorter scale it should be fairly comfortable.
Truth be told, there's no "bad" SS fret choice for bass, though 6100 and 6115 scare me, lol.
