The Driver has a slower meter speed, which is perfect for me. I had the R9 cannon which was very good, but the R11 has added a little more distance, sometimes quite alot. My longest drive with the R9 was 397yds in a Alt shot game so it wasn't registered (hmmm), hoping to get the Diamond award with the R11 lol.
Haven't noticed any strange movements in flight yet.
Perfect club to use off the Legend Tees, To tell you the truth it might be a bit too long on the shorter holes on the other Tees as you will have to use shorter swings and could cause troubles.
Once you get in the Level 80's it's a pain to reach the next one because of the number of points needed.. I'm on Level 88 with 398247 points, my next level up will be 428488.
Highly Recommended Club to use
Good Luck
