I use my friends grenade during open bowling when the lanes are dry. Very good ball for that. When there is a lot of oil on the lanes the grenade just seems to slide down the lane and slowly arc to the pocket, it just hits the pins instead of smashing them like most other modern balls. Of course the grenade is a urethane ball, not a reactive resin like 98% of today's balls.
If you play in a house with old wooden lanes the grenade would excel!
