My only recommendation is to go with the A391 pack over the A Custom pack. I had an A Custom pack for two years, and while they were great cymbals, I had difficulty getting them to produce some quite/lower dynamic stuff. I ultimately migrated to a set of giant K's, but am still eyeballing a set of A's once my budget allows them.
I'd also recommend Sabian AA's, but their pack doesn't include the 18", which makes it a very poor value.
Questions like these are similar to someone asking ME what kind of ice cream THEY should like.
Personally, I'd go for the Mocha Almond Fudge. (K) There are plenty of people who like Caramel Swirl, though, so you'd be safe if you chose that one, too. (A Custom)
