I use Bravado washable pads, and I love them. I have about 15 pairs. I leak alot. (Dd is 7.5 mos, and I have just now gotten to the point where I don't need to wear them in the afternoon and evening. I still leak so much in the morning that I have taken to holding a bottle under the other side at dd's first feed of the day. I usually get a good 20ml (~2/3oz).)
They are on the thick side so wearing them under tight tops is a bit iffy, but what I like the best is that they have a CoolMax lining that wicks the moisture away from the breast. They also retain their shape when washed and dried. I have some cotton flannel ones (I think they are Medela) that look like used tissues when they come out of the dryer.
One word of caution, though, with regard to pads with a moistureproof barrier (disposable or reusable), they are great for when you're out and don't want to deal with an embarrasing leak. However, they also hold moisture against your skin (both bm and sweat), so it's not a good idea to wear them 24/7.
