yeh i heard the flat top 12mm are like pushing a keyboard button - the raised ones are better - but tooooo big for me..
could probably get china to fabricate a flat top version of the clicky dome - but kinda makes you wonder what the market is for stuff like that, take for example that PVA mod project (er hem;-) 683 funders
I'm using a 12mm in an SX350 build and the best description is kinda mushy with no click. Don't like it much.
