If we assume cost (or rather, longevity) is not an issue, I would say go for all Swiss lace. French lace is very slightly more robust and very slightly more detectable, but the difference is small. There is a case to be made for thinskin pieces, but since you are already used to lace I would stick with lace for the first one, and you can experiment later. There is also a case to be made for ordering a poly horseshoe on the back and sides of your piece, especially if you sweat heavily (eg at the gym) and you're not too worried about detectability to the touch.

I can't judge the density from those small pics. Could you put up a full head picture (obviously blank out your actual face if you prefer)?
