Switching from an all Brown MX board to all Black MX board and back is weird enough, having them both in the same alpha key cluster is insane FOR TYPING and general use.
If you use a dedicated gaming keyboard, that changes the rules of what could work for you. If you don't use a dedicated gaming keyboard, having stiffer switches for WASD would get old before you could post a quick brown fox uber gaming nkro test.
[sarcasm] But I hear MX Reds or gold plated USB connectors are the best for gaming anyway. Or is there a new flavor of the month out? [/end sarcasm]
