They do make small form factor mechanicals, namely kailh choc. The only good choc switches in my opinion is choc navy and choc jade. As far as tactile topre is amazing, but I recommend that you at least try black alps, orange alps, or salmon alps. Those are all worth a try, but if you want a tactile hill similar to that of the hhkb, (or the 2015 mac) try t1 or aliaz. All viable options, but that is just scratching the surface, and you should do your own research, but don’t say that you only like tactile switches, if you havent tried others. When my only board was a tactile, I thought I did. Now tactile is my least favorite, but not because tastes change, but just because i hadn't tried the alternative.
