2000 Abralon Sanded.. drilled 45×5×50 with a 4 inch pin. On a house shot, it can be thrown down 10 board or hooked from board 15 to board 5 when the lanes start to transition. At the same time, I use it for my 10 pin which makes it a must have in any bowling arsenal.. fantastic bowling ball from Lane Masters/Legends. It's also the first bowling ball I start with.. I should have ordered two of them.. lol
