I have both the Imperial Eastman kit and the strap on master kit and The snap on kit wins hand down until you have to use it under the car. The imperial kit is really handy in tight places. I have it from my refrigeration repair days. I recently bought the snap on kit when I moved to Georgia and could not find squat for 6 months. The practice advise is good also. I still mess some up some times. I also bought the 3 tube strap on tubing bender. The radius is perfect for duplicating the COILS that you typically see between the master cyl and proportioning valve. It will also work on the metric tubing pretty good.
