I've had this ball for several months now and have a lot of good games on it. Here are the specs as I have them:
weight: 14 lb
pin: 3-4"
tw: 1-2 oz
drill: Ebonite pattern 1
Lanes: AMF synthetic, THS, 38', medium oil, 7 units on 7 outside boards
The specs above show the nominal conditions in my house, however, the conditions change depending on the 'condition' of the lane machine. Having hang spots and even oil strips going all the way to the pins is not unusual, causing a need to change to a completely different line, even on a THS. I've been very impressed with the versatility of the ball and the way it predictably responds to changes in ball surface, ball speed and hand position. Now that there are several new One series balls, there are alternatives to the 'original,' but I like this One. On a typical night, I stand 23, roll it over 17 at the arrows, swing it out to 7 and it makes a smooth, strong arc off the drier boards, carrying very well at 17mph. Nice ball.
I've found the best finish to be 2000 grit polished with Ebonite Factory Finish, though polishing overtop a 500-grit surface is also good. The published finish using polish over 4000 grit makes the ball too squirty for me.
