I'm going to suggest a different approach. Your not going to be able to make a considerable improvement in stage break down and speed in just one week. Add to that, switching to a new gun and going from Minor to Major and your asking alot of yourself in a short period. You already know your a bit slower, so capitalize on that and make every shot count. Focus on the A hits and no penalties and you may put yourself in a better position to beat your buddy. Hearing "2 Alpha" all the time your being scored will put the pressure on him more than " Charlie Delta" with an equal or slightly lesser time. This will also insure you will be taking less make up shots. Of course, this assumes that you are already an accurate shooter...... My 2cents, from another C class shooter!!!!
