Fading yourself is very difficult to do. You won't know what the hell you're thinking after a while.
As far as fading cappers goes, IMO it's much more difficult to fade a capper than follow him. You'll probably give up once they go on a small winning streak are all happy and shit and you'll wonder WTF you're doing on the short end of the stick.
Having said that, I think if you've got a mind, body, and soul made of cold stone, fading can be quite profitable.
Personally, I'd rather follow successful cappers who are going good. It's easier emotionally.
