Hi Cherrie,
I don't have an answer regarding plucking, but I was thinking you might want to consider giving electro another try. Like you, I also ended up with a number of gray hairs left over after laser and was worried about scarring from electrolysis. It took a couple tries to find an electrologist I trust, but it's possible to do electrology on sensitive skin without causing pitting and scarring. I wouldn't recommend straight thermolysis, but blend should be fine for most skin types.
If you want a good resource on anything hair removal related try searching the forums on hairtell.com. They're my goto site for anything hair related.
