We've had who is the best player you've ever played with and who you'd like to play with; but the question is who is in your regular 4 ball.

Where do you fit into the 4 ball on handicap? 1st, 2nd, 3rd or 4th.
Are they work colleagues/customers or guys you met at the club/course?
Do you play for money on the side?

As for me:

I'm ranked 2nd in my 4 ball.
Met them at the club
No money on the side during competitions; but will have a wager on golf trips or practice rounds during the week.

I play with the same group of guys on Thursday, Saturday, and Sunday. We have about six of us, so whoever shows up at the set times play. If we have five or six we play together a lot, playing different styles of games depending on how open the course is. The 2-6 guys are all close in handicap (between 0 and 8), but the 1 is a bit ahead of us with a +2. Great group of guys, great fun. We always are playing for something, but never for much. We met because of golf, but are a close group of friends that also hangs together away from the course.

I don't have a steady group. I usually play within 5 groups of guys at my club. Im usually one or two man, except when I tee it up with some of my pro buddies then Im 4!
