I drilled my Warlock XV to go long with heavy backend. I have to say this ball hits with extreme power and very forgiving. I use this ball when there is a little more oil or fresh oil on long patterns (39 or longer) this balls reads the lane well and boy does it store up the energy to hit the pocket with authority.
I would recommend this ball for all levels of bowlers
The only dislike came from a fellow bowler and that was its not scented lol
