Breaking things up is best if you have multiple classes and a number of athletes. That games I competed in had 3 classes (A's, B's and Masters) Master's started at stones, A's Sheaf and B's on Hammers. We saved the caber for the end.

Don't fear the sheaf or caber ;-) I'd say if its a bunch of inexperienced guys who are just out for fun, get a light caber--65-70 lbs 14-16 feet and have fun with it. Aye, watch the sheaf forks though--can get a nasty leg gash if you don't know what you're doing.

If these guys don't have a lot of experience--might be better to chuck 'em all into the same mix and march from event to event.

Post to the NASGA site on the AD forum and see what they say. Good luck!
