I want to make some official rules changes for slow combat. The old slow combat is no longer a valid event and should be replaced with the speed limit events that have been growing in participation. I don't to reinvent a new event, just modify what we already have. Right now, 329 slow combat is the same as 328 fast combat with these exceptions. Current is on the left, proposals on the right.
Current New 75mph rule replacement
Applicability, equipment, purpose, rules, procedures, and judging are the same as

Notching into the wing is permissible if safety is not compromised.

3. Procedure.
A kill does not end the match. Either or both competitors may score a kill in the
same match. Not more than one (1) kill may be scored by one (1) competitor in a
match. Once both strings have been cut, at a signal from the judge, both fliers
must fly level and counterclockwise. The fliers shall fly level and
counterclockwise in such a manner as to avoid midair collisions, near misses, etc.
4. Scoring.
A kill counts 100 points
