RDK, did you use more of the 5lb magnets then you did the bigger ones. My pilot math tells me that 2 5lb magnets would be just as strong as 1 10 lb magnet. So guys who are worried about trooping could if nessisary, just add a few more of the small ones without worrying about the over powering effect of the big ones.
Now this is usualy the point of my day when a flight test engineer tell me my math is wrong and calls me a meat servo.
