Very expensive, but I felt that if you made it through to race 5, you will get paid into the hundreds and it would be worth it. Race 5 is just too wide open anyways.
Very cheap.
Race 4 should see the 5 as heavy chaulky, but I like the other 3 and it can make a profit.
Last post, I said race 5 is wide open, but that's assuming 3and4 don't do what they're supposed to do.
Race 6, 4 don't break stride, should be an easy winner.
