This is awesome! Not that I mind, but just to be clear, are you scrapping the idea of heavier "regular" domes and going with just the BKE variant?
Either way, I'm definitely going to get a set for my Norbatouch. Torn as to whether I should go with all light (which will still be a little heavier than stock), light alphas and heavy mods, all heavy, or all light with just a single heavy for the spacebar like jchan is going to do. And maybe I need to get some for my FC660C...
