toomanytenpins, What is the pin to PAP distance? You say you moved every thing left and the pin is still right of your ring? If so then you are too close to your PAP if you are a low tracker. A low tracker 4 1/2 over and less than that will have a pin just to right of bridge centerline (above or below) or even above or below the middle finger to be the required 4 to 5" pin to PAP distance.....irregardless of the pictures in the drill sheet. I know this is confusing by Hammers pictures, but their directions are clear about keeping pin to PAP above 4. If you look at the low tracker layout...#8 it even shows the pin under middle finger. Pin under is better for spinner releases as it needs to get an earlier read, as well as pin positions that are bad for you when right of ring( which work great for higher track players. ) I drilled one #8 for a low track lefty and he loves it ...pin under middle and heart in track below thumb. My pin under ring NoMercy at 1000 abralon ( my PAP is 4 7/8 over and 7/8 up) is 4" from PAP and heart in track is a beast on oil. Once I lose the oil and can't chase it in deeper the ball starts to not recover, as all dull aggressive balls will do without enough oil. If your Power groove is hooking more with its high rg shiny cover and mild core, then your NoMercy with a dull surface a too close a pin to PAP( 2 1/2 to 3 1/2 ) is definitely burning up and loosing energy. It was probably burning up the previous night also. When shiny and weak out hooks your dull and powerful, you are burning up and quitting. Is it the ball that has died....I think not. It is hard to tell sometimes by the ball motion on the lane, but trust me, when I start to leave a flat ten, I check the ball when it returns and check the amount of oil (or lack of) on the ball. If I don't have some decent rings it is time to move in deeper to catch some oil, or time to put him away and go to something longer and weaker covered. I know it is frustrating, but I truly feel the ball is too dull for you, but if you shine it and play direct up the outside it will probably still read too earl with its low pin to PAP distance. As you are forced to swing it it burns up. Just my opinion and experience, Al
