The carbon crown is 50% lighter than any other driver on the market. What I love about the crown is that it has a very subtle look from the top. It is very simple looking but obviously the technology is in there. The biggest surprise is that it is very quick, it is around 3-4 mph faster than the other driver I tested. It is very playable and you get great distance on the course. I use the 9.5° driver with a Honma Vizard FD-7X shaft.
