Ausie, one thing about the Binary's. Regardless if you hit the draw stop, you can still move that bottom cam a little. This is one of the big debates with drop aways tied into the buss cable I've read about. My understanding is you lose let off doing this. You need to add twist back to the bus cable on the top cam to restore your let off. However, care must be taken to avoid going over 80% and risking a lock up.

Just a thought
