I swap out my boards once or twice a month, as I have a bunch of different layouts and switches, and I enjoy changing things up every now and then. I am currently using my Neo Ergo (tented alice) with MX Blacks (lubed 205g0, F+SS TX XL 70g w/ 105). I quite like the split layout and heavy switches as I type hard. Before that I was using my Sneakbox AVA (standard alice) with a tactile frankenswitch (Panda Stem and spring, cherry housing, lubed 3203, filmed). Before that was my Liberi (65XT) with Nixies (Lubed 205g0, Filmed). I came into the hobby wanting to try a bit of everything, and have pretty much achieved that with my builds, as I pretty much have a board in most common (and a few uncommon) layouts, with a mix of different linears and tactiles. No clickies tho. And I havent delved into Topre because I can't get used to the hhkb layout.
