I'm looking to get some nice looking, preferably pbt, keycaps for my quickfire rapid-i, but I want keycaps that don't let light shine through the keycap, or keycaps that look cool when light shines through them. Anyone have any recommendations for keycaps that look cool when backlit. Also are SP's DSA PBT blanks either thick enough to block out backlighting, or would they look cool with lights shining through them?
