Look very good. Pleasantly surprised that we can replace fittings with similar but don't have to purchase everything from the same brand. I think these look like a very good set of rules to allow the class to thrive. Tight enough to avoid an arms race but with enough freedom for a bit of personal preference.
Was interested to see C 1.4 - can always change down rig but not up. That's what we've decided after much debate to do at our club for most of our handicap series (that is series which last 8-10 weeks). You enter with the biggest rig you might use and that's the handicap you stay with.
(We made an exception for our once a month pursuit series because it would be too confusing to have different sailors starting at different times in the same rig if someone changed down but someone else didn't)
Hope you can get those handicap numbers to stick and be endorsed by official PY. I'm sailing off a lot lower at the moment.
