I've never had a bad batch of AF either... and i probably go through a 250 tub every 3 or 4 days.
and to answer your question: i'd pick your buddy.
if i gave 1 point to each flavor i liked, it'd go to each EXCEPT the orange and the watermelon. so that's 3 for you ((because you picked 2 of the same flavor... and grape isn't that great alone in my opinion)) and 4 for your buddy... so there ya go
but i hope you guys enjoy it, you still have a very wide mix of flavors to try so you're good to go.
