I always enjoy it when Barnes is in the booth.
As for 2 handed bowling, I think they all recognized the fact that Belmo has always bowled that way and has put a lot of work into his craft. His balance at the line is impeccable, his accuracy and ability to adjust is amazing and his spare shooting is spot on. If it was all because of 2 handers having a large pocket, then we would see more Osku, but Osku has spare shooting issues and I don't think he is as versatile.
Two handed is not easy, but if you can be accurate and pick up spares, there is most certainly an advantage. I know I won't be trying it anytime soon though, I have accuracy issues with one hand, lol.
Jason Couch annoyed me especially since he's a lefty and also had somewhat of an "advantage" during his career.
