Jeff,
I agree, that the average LPGA player would be hurt. But I'd have no intention for a shorter tee rule to be implemented on the LPGA. Much like the LDA players, the fact that the average LPGA player has such a high AOA suggest their direct pursuit in using AOA to try and gain more distance. With an average carry distance of 218, there isn't much of a public concern over the danger in how far the ladies hit it.
An implementation of a shorter tee rule would only apply to a select group of players, leaving 99% of the golfing public completely unaffected and still able to use a longer tee.
