I thought that was the knock against the Lezyne, that it was easy to unscrew the Presta valve as you were unscrewing the pump.

If the Road Morph head is tight, you can unscrew the cap about a quarter turn; it'll come off the valve easy after that. Probably a good idea to screw it back tight before you ride off, just to keep it from unscrewing (and being lost).
