My lower back is no happy at the moment, and it's all I can do to run some laps. BUT as soon as I'm able I will try all 4 layouts yall have liked. I too think 14 will be very quick, but those "bubble" corners in the loop can look easy but will bite you in the a$$ when trying to run tight lines!!!

ON a side note I had the electronic glitching ( acts like the receiver) again on my GLR. But it only happened when the battery was low. I charged both batteries along with an GL battery, and will test tonight and tomorrow to see if it is a low voltage issue.
