I recommend you buy multiple singles of as many as you can try. Usually 3-5 will give you a good idea. It took me a long time, but I've tried just about the entire HSA collection for regular production. You develop exactly which profiles you like, don't like, and are neutral about. There's not many I don't like admittedly, but there are for sure some i prefer over others, and some I probably wouldn't buy again. Also of note, our taste buds change every couple of years, so it's nice to come back to something you may not have enjoyed or preferred in previous years.
