I'm putting my wager on eggplant being another perfect bloom. I'd probably stick with the electric toothbrush.
Disassembling the bloom and manually applying pollen is something to do when breeding eggplant, not trying to get a crop in. But thats just my unwillingness to stuff my face in the dirt--talkin'.
For eggplant and others, I just smoosh my finger gently into one flower, in a non-destructive way, and then smoosh it gently into the other. Seems to work fine. I've heard of people using paintbrushes, but I've never understood why.
