Adding to that point, this also allows people to take a chance on hops they normally would not use without spending huge sums of money.... and they can expand their brewing horizon
I bought one of the friday night lights packs a while back. I only really wanted 2 of the 4 hops in the pack but I bought it because the price was right and I thought it would be nice to try the other two types. So that line of thinking is valid in my frame of reference.
I like the geographical pack idea. I dont care much about commercial brewery packs. You should definitly work up a pack for the new Cascadian dark ale style (or whatever the heck its called now-a-days).
I use lots of american hops. As others have mentioned, I would love to see an all English pack liek EKG, Northdown, Bramling Cross, target, Fuggles, ets. Or a Noble Pack. Nobles rock--not just because it is my last name.
