I have a set of pale blues, but I find the tactility nearly non-existent. The sound is excellent, and the weighting feels good(for someone who can enjoy stock clear switches), but the tactility feels less than even stock cherry blues. I am an alps fan, and I personally would not recommend pale blues if you like alps tactility. I am waiting for jades to restock, and I will report back then.
For a heavy switch, pale blues feel 'delicate', that is the best way to put it, and I think cherry switches are already 'delicate', but these go even further with the dainty feeling tactility but a very crisp and consistent click. They feel very refined, but I personally don't like the lack of tactility. It may be because the click is the tactility, and it is applied off axis on a switch that has remarkable stable stem wobble, but I simply can hardly feel it at all if wearing headphones. They almost feel like a linear switch. If deafened by closed headphones, even browns have more apparent tactility than pale blues, to put this into perspective, however, the tactility on browns is MUCH less consistent.
Pale blues definitely deserve the attention they are getting, they are great switches, but I don't think they will be for everyone. I am hoping the thick click bar version will inject some much needed tactility into them. I went with jades because pale blues are borderline too heavy, although it does actually feels pretty nice with light tactility, they feel very cushiony and not harsh at all. I could totally understand someone digging it. However, I actually usually like lighter switches, but 'light' is subjective. I find 60-65gf to be ideal, and jades land right in the middle, if the spec sheet is to be believed.
I hope the next batch doesn't have this 'stickiness' feeling I have heard about them. If that is the case, a spring swap isn't a huge issue. I also assume that a lighter spring will feel more tactile, as you will notice more when you leave the click spring. On pale blues, the spring is so heavy that by the time you leave the click spring, the spring is already compressed enough that you can't even notice a weighting change, hence the linear feeling to them.
I tried white switches on a friends keyboard, but I found the sound to be very high pitched with the clicking. Pale blues have a better sound, I assume because the heavier spring causes the plastic to ting at a lower pitch. Personally, I think pale blues rank as the best sounding cherry mx based switch, but still lower than alps switches. Alps sound is just so iconic, it's not even a fair fight.
