it would be very useful to see it in profile and the shape but I think you are right … the Triplet is actually the YYR with the diameter of the flat part of the inner cup greater than all other models of this type (Gleipnir, Clash 2012, Star Geyser, etc.).
p.s. but what model is this ??? I’ve been thinking about it for weeks … and this tilt of the rim tells me something but … I can’t remember!
