My hair is not think at the sides anymore - I will have to take some new pics to show. It's very light and my temples are totally gone.
SFS front and #64 base because I like the combo. I found the SFS all over units to be a little light, flimsy and harder to attach and to get a solid hold. The French is a little more solid.
By the way, I would never dump a unit because of a bad base. The base does not matter at all!! I have had a unit before with lots of holes, and with a very badly frayed hairline, and still it looked awesome because the hair was good. Hair is kind, base doesn't matter. People should never worry about the fraying of the unit or holes. You only need to worry if it develops bald patches.
However, once the hair is bad I will dump a unit.
[Another hair supplier] have me a unit a few years ago. After three weeks of wear, it looked like a birds nest. It was a tangled mess and even after untangling it, the hair was dry and it looked terrible!
