I also have flown with the Bill Young Handle and a host of other electronic control systems. I have a friend who flies his Piper cub (80" span) with a 2.4 Ghz radio and reports that the line tension is reduced since you don't have the nylon coating on the lines.
There is a rule proposal at the AMA to allow 2.4 Ghz to allow in CL general and another proposal that would allow 2.4 Ghz for CL scale. Write your contest board member on your thoughts so they know how to vote.
After flying with electronic controls (regardless what format, Bill Young, JR DSC, servo driver, etc...) I would never build a 3-line airplane again.
Here is a link to my book that I wrote on CL electronic controls, it talks about line construction and some of the information is now dated and obsolete, but a few chapters still apply today.
I currently fly with the JR radios with the DSC connection and insulated lines, and also use the Servo drivers.
I have recently converted to electric power with the brushless motors and Lipo batteries, best thing I did especially for scale.
