Title: What is this drilling pattern?
Post by: jt23 on April 08, 2008, 12:53:53 AM

This is a columbia EGO. Could anyone tell what bowling style is this ball drilled for? Its for a lefty.  Its a for-sale used ball that fits my span and im thinking about purchasing it.

Looks like a typical label leverage drill, or maybe a label shift, since the cg's not on centerline.

Nothing special. Gives you a nice smooth arc on THS shot. About average length. This is a very common starter drill.

Duct tape is like 'The Force'. It has a light side and a dark side, but it still holds the universe together.

It appears to be a lefty label drilling.

Need a PAP and info if lefty or righty. Without this benchmark it is hard to say or even guess what the ball is supposed to do.

A bit dizzy today, dizzy?

It's marked in the original post that it's for a lefty!

I've upped my average, so up yours!

Depending on the bowler's PAP, it looks a little more like it could be about
4 1/2 by 5 1/2.

It's a no-flare drill for a righty!

If the lanes have light to medium light oil, with a well defined dry area,
if the bowler does not have high ball speed,
if the bowler does not have a high axis tilt,
if the bowler does not have a lot of side rotation,
if the bowler have average or so rev rate (250 - 300),
and if the bowler's PAP is in the 4.5" - 5" range without an inverted track,
THEN this ball could be usable on light to medium light oil with decent length and medium backend.

There are 4 o 8 more sets of potential IFs/Thens. You must give more information about the bowler and the oil pattern for ANYONE to give a semi-reasonable reply.
