OK, I'm not going to pretend I fully understand the subtle differences between RSMPPS and CPPSRB.  I do feel that either of these should make for an agreeable compromise between the current (demonstrably broken) SMPPS and any of the AM variants. As someone that plans to keep mining here long term, I would of course prefer to cut off the inactive leaches by going full AM, I would be content to switch to one of these "recent" versions.

Also, I thought one of the major reasons to change reward system to PPLNS was to get rid of the infinitely growing shares database. I don't see any of these PPS variants helping in this respect. Then again if keeping the shares database also means we keep the current stats, then that would be a nice plus, at least until we have a new stats system in place, tested and tweaked to work with whatever reward system is in this pool's future.

Whatever the final decision may be, I hope something can be done before even more miners switch to another pool.
