It would take some digging in to AMA sanction rules, but I believe the one sequence and land option would have to apply equally to all contestants. I don't think a singular exception (for electric) would, or should be be allowed. Flying one sequence rounds contest wide allows for both electric and IC powered models to compete on an equal footing. I don't believe you would run in to much resistance to one sequence rounds, especially in the SC.Don't worry! I plan on putting the screws on Cam to get me an allowance to do that! But, before I build a 40% and electrify it, there will have to be a more permanent solution!
One of the reasons they did it that way at the Worlds Fly-off was so that contestants flew in front of a greater number and more diverse set of judges, which is another benefit to one sequence rounds. It's a little more work for the CD to create a judging matrix though.
