How steep do you think the price of victory is against big business?

Would you for the victory or the money? If there was an issue with a rather large company and you knew you were in the right but didn’t have the money to go after them, but a rather potent attorney (maybe on the border of being egotistical) chose to represent you pro bono but when you win (and he he is so sure of it you can bet he is out shopping for a new Jag already) he gets 65% and you get the satisfaction you brought big business to its knees and made them capitulate. To be right worth potentially 10s to 100s of thousands of dollars or being made merchandise by some attorney makes the price of being right to steep?
