I used to open up like that when I stood left and threw right. I was also donating money in tournaments at the time and told myself I wouldn't do any more until I could throw straight up and in.
I had the luxury of a gold level coach who was hanging out after our league night ended, who stayed to bowl with our team (he was a friend of a teammate).
He gave me things to work on in practice that worked out well. I have a very diverse game now, but my average has dropped 10 pins since last fall.
Sounds bad, but I don't have anymore 225, 170, 190 set nights like I used to. I'm much more consistent now with my scores.
In perspective, I was averaging 205 on the THS and 158 on my sport league. Now I average 195 on the THS (through Summer) and have shot very well in the two tournaments I've bowled in recently. I don't have any sport league averages since the change, but I feel confident in that I can line up on any pattern out there now. I just have to learn how to move as they break down.
I placed 4th in a city tournament with a 209, 267, 268 (straight up the 8 board) and 4th in the Largo ProAm with a 193, 180, 186 on the Shark pattern (I played this one across the middle with an open stance). WRW was on the pair next to me, what an awesome experience
What does all this mean? If you want to smoke up the house shot in league, then keep on keepin on. I would highly recommend that you consider learning how to square up and be more diverse if you want to compete in tournaments and continue to work on playing many different lines.
I will average higher in the next year once I become more familiar with the drastic changes I've made to my game.
I also recommend you try to find two houses in your area that accommodate swinging the shot and playing it down and in so you can work on both lines. I throw straight up 5 on synthetics and hook the lane on the old guardian.
It doesn't have to be an unbreakable habit.
