CoyoteOldMan The IMS does have a single. But, I use the stock single as bottomless, if my family or friends ask for a smaller cup with milk. I often load 11g but rare 12g. The 11g is perfect as long as it is nit a dark roast or a decaf.
The Motta tamper will be 54 mm, right? If yes, it won’t. The stock requires at least 54.4 and the IMS 54.9! I have a Torr for 54.4 and Bravo for 54.9. 😊
