How about this to fix the "luck of the coin flip" problem in the leg clinch.

Just model greco and have the ordered hold position at 1:00 and reversed at 1:30 of each period. No period could end less than 1-1, with the last to score winning the period. It would also make the flurries in the last :30 more intense as the losing wrestler will have the opportunity to make up the points whichever position they are in.
