This is just out of curiosity. Is there anything about your cup (please specify which cup!) that you really dislike?
I'm looking into getting a second cup and I think this might help eliminate some of my options :D. It's sooo hard to decide which one to get!
I currently use a large MCUK, and the thing I dislike about it is the low capacity (for my two heavy days). Other than that, I have no complaints.
