A few days ago I played a local municipal course that had an R11 for demo with 10.5 degree loft and fujikura regular flex shaft. I jumped at the chance to play a full round with this driver since I have heard good things about it. I didn't try to bother with adjusting the club, I left the settings to neutral and standard loft.
Playing with this club was AWESOME. I was ready to buy this driver after only a couple of tee box shots going longer and straighter into the fairway.
After playing with this driver I'm curious if there are any differences between the R11 and the Burner 2.0 besides the adjustability features on the R11. If the Burner 2.0 is the same club without being adjustable I'd rather make a purchase on that club instead as I don't see myself taking full advantage of the R11's features.
