I'd prefer manual as the electric grinders are too big for my small space. I'll try using 17g. I hope it doesn't make it too weak.
My current workaround it to grind about a quarter of the beans at 7 and the rest at 8. It's soo annoying
Edit: So the 17g shot pulled OK. Its not as rich as I like buy I'll get used to it until I can find one of the 1zpresso grinders at a good price.
