Thanks for the explanation, Sam! Sorry for throwing a spanner in the works...
To be honest, my ultimate dream version of this set would use Row 1 for F-keys AND numbers, row 2 for top row alphas, row 3 for mid, row 4 for bottom row alphas AND mods with row 3 spacebar, something like this:
But I'm aware it will not be feasible for this GB. Also, it seems SP don't have molds for a 2x row 1 key, so backspace can't be row 1....
My big gripe is typing on non-sculpted alphas, particularly the bottom row of alphas for some reason.
But then again, the picture rowdy posted looks so darn good..... I'd order a sculpted kit even though it will have different surface finish on certain keys (1.25x mods have to be matte). SP's "matte" finish SA profile keys have semi-matte sides, just the top surface is matte, so they won't look out of place, IMHO.
