Almost as good as my ERC, which was banned by the USGA.
I still have an ERC 3 wood, 12.5 degree loft and a stiff shaft. The USGA didn't ban the ERC fairway woods, only the driver.
8.5 degrees huh? I may have been better off going for a lesser loft myself. I never thought I would have the trajectory with this driver that I do. Out of curiosity, do you know your swing speed? I was trying out the R7Quad the other day and I was told it fit me perfect cause my swing speed was 115 mph. It really takes a liking to people who swing over 100 mph. I know I have a ton of problems when I try other peoples clubs and they have regular flex shafts cause they're too whippy. Oh well, I'm carrying on a bit too much....lol.
