I have paper traded Pitbull about 2 months. During that time, it has made an annualized profit of over 100% virtually every week. I now have *real* money in an account (as of this week), but it is too soon to tell results.
I have found Pitbull to be exactly as Henry says. Simple, easy to learn, and effective. It is well worth the $49 he charges, and more IMO. Good luck with your investments.
