Up is a tour issue triple diamond flash driver. I caddie in Houston area and had the privilege of working for 1979 masters champion and he gave me this head the week it came out. I've not used this I did buy the shaft directly from Mitsubishi with the intent of gaming this and found something else that works for me. The shaft is a tensei ck pro orange 70tx shaft. It is 9.99 out of 10 nearly perfect. I spent at that time 300 on the shaft alone. It does have a tour issue red line adaptor as well.
