2) *We combined the standard, and FAI classes into one class and there
is no provision for taking this into consideration when choosing a
weight. *You cannot have a separate weight for each sub-class and in
this case the standard or 15 meter ships would have a big advantage.


Actually the RC is one step ahead of the game this time. From the
rules appendix,

"In a mixed class (e.g. 15/18) regional, the CD may set different
weights for gliders
from each class, to establish a roughly equivalent wing loading."

That said, the partial ballast rule is really intended to address
unusual conditions such as a very soft field that makes full ballast
takeoffs unsafe. (Cesar Creek 2010). It's intentionally rough-and-
ready for this reason. The RC did not put in a wing loading limit,
which might be fairer, because telling everyone and the scales team at
9 am to figure out their weight at 8.25 lbs/ft^2 and grid at noon
would be a disaster. It's better in the majority of cases to decide
water or no water and keep it simple.
