So upon receiving the Kailh Pro Burgundy switches I ordered, I realised that they were really bad. They fell terrible to bottom out, and they travel a lot less. They're also pretty inconsistent and they feel scratchy in all the wrong places, too.
But I put a spare Greetech Black slider and spring in there and holy fudgenuggets does it feel good. It's incredible smooth, much better than a Cherry Black an a touch smoother than Gateron, and the weighting is very nice too, also better than a Cherry Black.
By itself, the housing is the Achilles Heel of the otherwise magnificent Greetech switches, when you put them into a nicer housing the difference is night and day. I like these so much that I'm going to build my Let's Split with these, instead of the Burgundys.
