Having briefly read the very long and technical article, I find the following:

Ted is correct is his contention that the combination of heavy models, high power, and short lines places some models in a dangerous condition.
Ted is correct is his contention that the 60 MPH speed limit, which is essentially impossible to enforce with certainly, is an unacceptable way to rationalize flying heavy models on short thin lines.

I believe Ted's proposal doesn't do enough to formally ban the use of short lines on heavy models.  This is one practice that can drastically increase stress on the lines.  I have no knowledge of anybody actually using short lines on on heavy models, but if we're closing the loopholes we should cover this at this time.  Here is my opening offer:

Up to 0.5 pound minimum length 25'
0.5 to 1.0 pounds minimum length 35'.
1.0 to 2.5 pounds minimum length 52'.
2.5 to 8 pounds minimum length 60'.
5 to 8 pounds minimum length 65'.
8 to 12 pounds minimum length 70'.

I'm already in compliance with both Ted's proposal and my amendment.  I'm sure most other scale flyers are, too. Who wants to spend all that time & money on a model and destroy it trying to skimp on lines?  Leave that to the stunters.

Lines are chump change in the world of what you pay for a scale plane.  F2D flyer wreck four sets of lines a routine contest and think nothing of it.  Speed and racing have automatic line upgrades when somebody sets a new record.   

I don't believe that leadouts are required in any event.  Some people hook up direct to the bellcrank without leadouts.  I assume that leadouts are part of the line and therefore subject to the same minimums.
