Oh,
He just adopted it about 4 years ago and loves the power!
I would not describe him as average.
As to likening throwing the ridiculous backward method that leads to mostly mediocre results vs. Throwing powerful thrilling strikes and averages near 240 on league shots and championship titles in the PBA tour is quite a different thing.
I would think of two handed bowling like the two handed backhand in tennis. Why would you use just one! I believe it was MO Pinel who said a while back that "someday in the future we will see a person bowling 1 handed and say why would he do that.?" Attempt at paraphrase.
Obviously if one starts to experience the pains and aches of old age they can always go back to 1 handed.
By the way have you seen Walter Ray throw two handed? Not bad!

Yes I have seen Walter throw it two hands, and he doesn't throw it all that fast. Plus, again, Walter isn't your typical bowler nor is he in the same shape of your typical 57 year old, either.
People who have been spending their whole young lives throwing it two handed, aren't just going to switch to one hand, to continue bowling, if they find they can't physically do it. That isn't consistent with typical human behavior.
You are forgetting the main reason why people throw it two handed in the first place, as you stated in your original post, they get a lot of hook with minimal time put in to the learning curve.
It takes years to perfect a delivery to the likes of an Amleto, Robert Smith or in today's game, Malott, Kent, or Tackett. The two handed delivery is a quick fix to hooking the ball.
And as far as the stats of the two handed players; the kind of oil, and where the majority of oil on the lane plays the tightest, is a big factor of why the high rev rate is so successful on today's tour.
