Ahh, thank you for the new link.
I see the picture now.
So a break point at 7 or 8?
Actually I generally have a lot of difficulty throwing a ball out and getting it to come back at Poway.
My Full Roller style is much more straight and unless the lane is bone dry I can't roll over 10 and out to 7 and expect it to come back.
The ball generally will just fade out to the right or come back so weak it will just bounce off causing trouble.
Of course I never use reactive gear at Poway since it is so dry there.
But on nice houses like Kearny or Parkway in San Diego I can use reactive and fade the ball out as you sugest.
Here I am at Kearny on a perfect house shot using my Marvel S and you can see the ball goes out to 7 and grabs hard and rushes the pocket:https://www.youtube.com/watch?v=BiJjnKsCpuQ
But here is Poway. I find I have to stay around second arrow or inside to get grab in the back end.
For some reason the back end in the middle of the lane is very reactive but on the outsides the backend has little grab.
This is with my 1980's AMF Angle Plus urethane ball at stock grit:https://www.youtube.com/watch?v=nSfKv_-od7s
