As a multi-sport official (FB, BBB/GBB,
VB, SP Softball and formerly BB), I love working FB just for the fact that you have three/four other officials working with you. Not only is it fun during the game, but driving to and from the games with your partners makes for an enjoyable Friday night.
The only drawback is that as a crew you may only work 8-9 games per season, where you make work 150-200 SB games, 40-50 BB games and possibly 30-40
VB games, so you do have to dig into the rules/casebook a lot more.
My advice - try it for a season and I'll bet that you won't want the season to end (unless you have a playoff game in six inches of snow - which seems to happen quite often in SD).
