Glad you like Altar I!

They feel quite different to the Chocs, unsurprisingly. Although the required actuation force is close to the Choc Reds (40gf on our switch vs 50gf on the Choc Reds), because it's spread over such a small vertical travel it feels much "snappier". There is also very little pre-travel. It's kind of like a much sharper/tactile feeling chiclet switch with more vertical travel, if that makes sense.
