Nothing new, too busy racing and doing work for other guys.
The opposed crank is actually even harder to balance than a single. With the two crank journals and the weights so far apart if you get them off then it will twist on the crank ...kind of hard to explain. I talked with Tommy "The King of all things Balanced" , and he talked to them reallly smart fellars he knows, and the only way to properly balance an oppy crank is on a computer balancer...
As for the singles...any weight you take off of one side has to come off of the other, on the Oppy i do this by drilling the crank pins. Thwe opposed has 1-5/8 crank pins - HUGE! The singles are prone to breakage without a hole in them, I would not suggest that!
