Over here in England, most of the high-scoring lefthanders play out to the very edge of the lane, and let the ball swing in. Dependant on the amount of hook, they either play straight down the edge and let it roll up, or swing it out to the edge and back, and most of them seem to just switch ball and pace, but keep the same line. I almost never see them play tight through the middle. I guess I have two questions with this in mind:-

1) DO fewer lefties play tight through the middle because of the movement of oil caused by righthanders playing around the middle

                              AND

2) COuld a righthander do the same thing? Instead of moving your shot, could you just play an extreme edge of lane shot and just change ball and speed and still be competitive? It just seems to me that almost all right handers now play a out and in shot, and it is leaving a big space out on the edge that few people seem to play?

RC you just have to try all the angles on the lane to find the one most productive. That most productive line could be down the twig or from 22 at the arrows to the 3 board at the breakpoint 40 feet down the lane. To be at the top in this game you have to learn to play all the angles. That goes for lefties too. I teach the lefties I coach to get in front of the ball return when they need to just like the right handed players.
Most lefties never learn to bowl inside the 3rd arrow because they don't have to for league shots. If they bowl on flatter patterns at higher levels like the PBA then it's best if they learn it all. If you are bowling for a living you have to earn your check every week. People that only know how to play one way are just waiting for their check to come in the mail. Meaning that they have to wait for "their pattern" to come around. You can starve to death like that. Now if bowling paid as much as golf it may be a different story.

I don't understand why they don't put down triple the units on the right on house shot as they do the left.  

I bowled late last night and the righties had no shot at all.  The lanes were so dry that they had to play 30 and noone had a chance at carry once they got there.  The energy was gone out of their ball before it hit the pocket.  As a lefty, I still had a little something even though I was in at 15 out to 5 with a dry lane ball and throwing it so hard and taking hand out of the ball.
