So the quick change kit is really good but it seems the bit is designed to click so you will buy more. I've done 3 or 4 holes in the last 6 months. There is a 1/4 inch to 3/16 inch step at the tip, probably to make starting the first hole easier. However, once you get the first shot down, unless you're perfectly straight and have perfect trigger control, the 1/4" portion will grab and snap the club. A regular 1/4 inch end will likely lengthen the racquet. much longer. From now on I will be looking for third party beats.
