If it helps I like uniform boards but I don't mind other switch types on some keys. But I have limits. The only keys that I can do a different switch type are keys where you normally lift your hand from home row to hit. IE on TKL or full sized boards the nav block, arrow keys, the ten key side, and the ESC key. Also for me the space bar has to have the same switch type (linear, tactile, clicky) but can have a heavier spring. The one exception to this is my Orbweave has reds on WASD and either clears or ergo clears on the other switches. But that is strictly a gaming pad.
