I have a BW solid and a BWP I am needing a ball to go to when the lanes break down. I have a Backlash but it is drilled weak. I have a friend who will give me a Track 505 c , so which ball would be stronger. I will have to get whatever one I pick re drilled. Or is there a better ball ? I bowl on a ths with med oil. I am a stroker with a high ball track and roll it about 15 mph.Thanks
