Jim,
I think your premise that the recession (and the downturn in turnover driven by Tiger's problems) will make manufacturers less litigious is flawed. My experience (and I am a litigator, albeit not in the USA) is that litigation is counter-cyclic, businesses are more, rather than less, inclined to litigate when times are hard. In fact, I suspect that the USGA's willingness to become embroiled in litigation is rather more likely to be reduced, rather than the manufacturers. Add to that that Tiger was more likely than most to desire a rollback (since it would be likely to emphasise his superiority) and he will, presumably, be less influential than before and I'm afraid I think roll-back has become less, rather than more, likely.
