I think it is a bit different for men and women and men can often get away with having very thick eyebrows, like that guy from the OC. Some women have thick eyebrows and it looks good on them too.

If you want to try it maybe you could do what a friend of mine does, she CUTS the bottom layer of her eyebrow hairs rather than plucks them (a pain thing perhaps?) and that way if you don't like it they will grow back.
