Silly question: While DCS is perhaps the most "OEM-like" profile, might we want to consider DSA or even all-row-3 SA?
Being a single profile, that potentially increases the odds SP will have the right molds to cover everything, and it makes it far easier to support different layouts, both user-choice (DVORAK, COLEMAK) and international.
Do they have a master list of the molds they have on file that will take ALPS stems?
