I quite like the Keycool OEM caps, medium thickness PBT and POM (particularly the POM), but prefer SP DCS and Cherry profiles. The lower profiles somehow seem to suit me better, almost as if they reduce key travel, even though I know it doesn't really.
I don't like any of the stock caps that came with my boards. Thin OEM profile ABS just doesn't do it for me.
Medium to thick PBT or POM OEM profile is acceptable. Thin DCS ABS I can live with, too. Thick Cherry profile POM or PBT.... mmmm, good.
That TAI HAO Dolch set is tempting (I love the Dolch colour combination), but I'm going to hold out for Ivan's Cherry profile doubleshot (GMK) Dolch GB
