I think it will have some success because the same people who do not understand Sport won't really understand that they're not bowling on the exact same conditions as the pros. But they will think they're as good as the pros when they put up the occasional number that beats what the pros shot on TV
The PBA shots can also be a stepping stone to sport shots. I think sport patterns are to rude of an awakening for a lot of bowlers. Heck, the PBA shots are going to be a rude awakening for most bowlers. I bowl on 2 non-house shots now. One is 3:1/4:1 and the other is 5:1. On the 5:1 shot, I'm averaging around 210 and there are people there that think the shot is to tough. I'm averaging about 200 on the harder shot and generally average between 180 and 190 on a sport shot.
I personally don't mind averaging lower. You just have to have the right perspective going into it. But I think there's a lot of people who get on a sport shot and really have no idea what to do. They've never tried to play straighter, they've never before usnderstood that they don't have great acuracy or consistancy, and they feel stupid not being able to hit the head pin.
So hopefully PBA patterns are a way to groom people for sport bowling.
As for them promoting it better, I'd bet that's because it's more promotable. Yes, telling people they're bowling on the same thing that the pros bowl on is a gimmick, but it's a gimmick that I think will work.
