I think I'll be heading to the Bridgestone Invitational World Golf Championship at Firestone CC at the beginning of August. I've done marshalling before at a PGA event, but the rules state no cameras Thursday-Sunday. I was planning on going on the Wednesday practice session where cameras are allowed. My gear is limited to an 18-55 kit lens and an 85 1.8. i may be able to use a co-workers 70-300 (non L) to get better shots.
What I'm wondering is A) With private practice Monday and Tuesday, do the more popular golfers even practice on Wednesdays? and B) what are some starting points to try and use regarding aperature, speed, etc. I know not to click during the swing, but also figure to captur the club moving in any way, I'll have to shoot at a decent speed.
I don't want to take 1200 images only to come home and have 10 users. 
Would like 120 if possible.
