MB, I think if you gave triples or rotation a chance you would find taht although there are "gimmicks" (much like in singles) there is a wealth of depth in that format. Everyone has their own opinion, I am not a big fan of singles or doubles. Just be careful you don't offend too many people by shooting down their favorite type of battle.
Hope the tutoring really takes off since you seem to enjoy it. I might try it later on, but I am probably way too busy now. I am trying to get a top 100 in the rated GBU, so I will probably be busy thru the end of March
