HB and YJ .. i have a feeling there is confusion between best ball and scramble.
Best Ball has been around since 4 player matches began. Best Ball = you use the best score from a 2 man team to determine the winning team for each hole.
Scramble = for a 2 man team means ... you both tee off and select the best shot ... both hit from that point and continue in the same fashion until you putt out. It's a good "golf outing" format for playing with a combination of golfers and non-golfers.
Most people confuse the 2 because they believe they pick the "best ball" to hit their next shot from.
Either way ... I'm not a fan of a Scramble since you always wind up playing the best golfers shots for most of the game. Since you can already play Best Ball (4 ball) and now with alt shot (2 ball) ... you can really do a nice tournament now on WGT.
