Oh and in response to your reply to me CSSDoctor, I don't know my swing speed, it's on my golfing to-do list. Thanks for the recommendations on the different golf balls, I'll see if I can get a 3-pack of each one you recommended so that I can try them out.
My teaching pro obviously has a launch monitor (GC2 with HMT) so I get my club speed data when I have lessons, but if you can get on a launch monitor somewhere and do a gapping session it will not only give you your swing speed, but will also give you your average club distances as well - very useful to know when you are on the course if you are serious about improving
I don't have mine yet, but have a rough idea based on average distance carry from my lessons with my 6i (180yd) so I work out each of the other clubs from that on a guess of 10yds difference per club. This, combined with my GPS watch has seen my scores get very close to breaking 80 this year (would have had a 78 if it wasn't for 2 bad shots a couple rounds ago)
There are plenty of decent quality balls out there these days, so if you can get your hands on a few of them to try it is certainly fun to try them
Callaway Chrome Soft (I want to get some of the yellow/black Truvis ones to try after seeing someone playing them at our golf outing last weekend)
Taylormade - Project (a), TP, TPx
Srixon - Q-star, Z-star, AD333 Tour
Bridgestone - B330 and B330S, B330RX and B330RXS
Wilson Staff - The DX range, Wilson Duo
Never seen or tried them, but I have heard positive things about Vice golf balls from a golf forum I am a member of
