top weight and Pin placements

[rcstricklin]

I would like to see some images of different pin placements and top weights on bowling balls. Also some compare and contrasts on each of these weights and placements.

[dizzyfugu]

Top weight is concerning internal weight distribution of a ball around teh pin area, so a pic won't help at all. As for pin placements, this is always relative to your Positive Axis Point (PAP) and the grip center. Putting the pin closer/further way from your PAP as well as putting it below or above the fingers have influence on the overall ball reaction and the delay of this reaction on the lane. Placement of the core's mass bias or the center of gravity will also affect ball reaction shape.

Since it all is relative, pictures won't give you much information, since a ball is only "good" for the player who uses it.

A great introduction about pin placement offers Lanemasters (got a bit hidden after website relaunch):

Thank you for the for the instructions. they have been really helpful. Things are finally starting to make a little since now. I guess my driller actually knows what he is doing after all. He never really asked to many questions ans still to this day hasn't seen me throw a one ball down the lane. But yet they still seem to come through.

You're probably bowling on a house shot.  Almost any ball with any drill will work acceptably well on a house shot.  So long as the ball's oil handling capabilities are within four or five grades, the house shot is the great ball equalizer.

So what would you call this ball as far as top weight and pin placement? It looks totally different from my ball that I own. My pin, CG, and MB are all pretty much in a line with the CG kicked about an 1" to 1 1/2" to the left.

"ALMOST" has sooooo very many meanings in this situation .....

WHat does "4 or 5 grades" mean??

There are many gradations of variations betweEn the average negligent house shot and THE GREAT WALL OF CHINA.

I'd call that ball a blem.  On a first quality ball, no more than an inch or so out of line.  Before I got that ball drilled, I'd have it weighed to determine the correct CG and top weight, and if a deTerminator is available, I'd have it spun to find the correct MB.  It's hard to believe that ball even left the factory if those markings are accurate.  I might not even call that ball second quality.

This surely is a blem, but shelley is right: have it weighed at a pro shop just to make sure the engravings are correct!

Otherwise, drilling options are limited and even if teh ball was drilled to be leagl, the reaction can be inconsistent - and this already occurs when the CG is less off-line between pin and PSA marker.
