Syllabus23,

Not knocking what you are doing, you say you are grinding a small profit, good on you, but to me it doesn't make sense.
You back three nags, 1 for 105% profit, 1 for 100% profit, and 1 for money back.
I back 1 nag with 3 chances, min profit 100%, but usually 140%+ profit and I have actually had a 600% profit.
Have you ever looked at place betting.

Cheers
