Hm, originally I considered using light domes for alphas + arrow keys, and heavy domes for F-keys and the 'Insert'/'Print Screen' blocks. But now that the moment as arrived, I'm concerned that the 15g difference between the two will be a bit much.
I'm curious, for those of you that have placed your orders, what did you decide on?
I could try a sample pack, but I have my doubts that pressing on the domes directly will be representative of what it would be like to type on in practice (that is, unless I open up my NT and cut the existing sheet, close the case back up, etc...).
