We last voted on our rules in 2005, and are indeed due for a review. We have talked about doing a review now and then. I don't think we have much disagreement about jumping though.
Things that seem to draw controversy though, include:
1. Whether an object ball flying off the table is considered a foul or not
2. How to word requirements of making a legal shot when balls are frozen
3. How to handle illegal pinching of an object ball to the pocket point or intentional double hit, etc
4. How to handle object balls being "accidentally" moved -- and whether or not moving one or more object balls is even considered a foul or not
Since we created our rules, they appear to have been adopted by all of the major tournament directors, either directly as we created them, or in some cases indirectly, as they "wrote" their own slight variations of our rules as their own, but consistent with most of the principles of ours. The BCA rules for One Pocket don't seem to have changed much, so they still remain woefully inadequate and out of touch -- the very reasons we created ours in the first place.
The CSI rules that the US Open One Pocket uses are very closely based on ours, but they have a couple of new ideas which are worth looking at adopting in ours. One relates to which ball to spot if all the balls are behind the line in a scratch situation, and another relates to the illegal pinching of object balls (and the like). The CSI rules are here:
