I agree with you Josh. Nearly all Vx climbs are unnecessary and are for show off at fly-ins or when you are flying with your Super Cub buddy. I'll admit I do them often just to keep in practice and make sure I can hold a nice steady Vx airspeed in the rare case I would ever really need to do it. I fly a lot in the mountains, but would never deliberately use an airstrip where Vx is required. However, that said, I can see where a pilot thru his own stupidity or inattention could get trapped in a blind canyon with no turnaround room and maybe need to do a Vx climb to clear the ridge. Stuff happens, so we do need to have the skills to fly at the edge of the envelope. Just my 2 c.
