HHs are hand hammered, K type cymbals, and are generally more expensive than A.s or AAs-- whether they're what you want is up to your taste. HHs are generally darker and funkier, A.s and AAs are generally cleaner and brighter. If you are certain you're getting a good used price on the HHs, you can always buy them and resell them if you don't like them. They should be good cymbals that you can use for anything, even if they end up being a little dark for your taste. I don't think you can go very wrong with them if the price is good.
