That reminds me of the Revisionist History episode "The Big Man Can't Shoot" which is about how Rick Barry shoots underhand free throws in basketball. It's a Malcolm Gladwell podcast, so take it with a pinch of salt, but his point is that the underhand method is far superior and still no one uses it because they're afraid it looks ridiculous.
In short: keep doing it the ridiculous way and ignore the serious bowlers ;)
