I gues using 0402, 0603, 0805 doesnt make too much difference to the design, other than the bigger, the easier for the DIY'er?
Yeah, I was thinking this too - any reason those can't be all 0603 or larger?
Also, what supplier is ES? I'm not familiar with that abbreviation.
man i can't wait to get my hands on the cad files.. i'm going to have to play around with kicad in the mean time to get used to it
