Tom, what you should do here is refund the people who had % in your second bullet & take the money of all those in the first bullet
But in all fairness, was a bit guttering to see this & I don't think you thought it through. I did not budget for a second bullet myself, but if I had busted as early as you did, then it does leave you in an awkward situation. Obviously within yourself you did not expect to be busting that early & I know personally you can;t afford two bullets, so when an oppurtunity arises for a possible second bullet, you are not going to turn it down.
I think what you should perhaps done like Keith said is give it a bit more time. If you had given a bit more time & was sure original backers would want a piece, then I would have lended you the money to buy in.
I hope this does not put anyone off backing you as I think you are a good horse to be on. I think like me & Craig said over the dinner break, would be happy to stake again if anything arises.
