ekau ni nak carik berat bape? duk kat ne?

double ade,triple pun ada

the length and breakpoint shape mostly depending on your drilling.. 3 1/4" PIN to PAP will give you the most aggressive angular snap.. 4" to 5 1/2" pin to PAP will give you a later snap which will then give you an extremely sharp breakpoint shape..

other than drilling you must see the differential rg of the ball.. 0.050 or 0.060 will give you a more arc breakpoint shape because the track is extremely high.. balls with 0.040 differential rg will mostly give a nice sharp breakpoint.

usually you see the pin to PAP.. the most aggressive drilling is 3 1/4" PIN to PAP..

I always like this example.. imagine a pen.. the PIN is the pen tip.. you point the tip up 45 degrees.. that is 3 1/4" pin to PAP setup... now imagine the pencil is in the ball.. when you roll the ball straight.. then pencil will be going up and down up and down isnt? thats how the core of the ball acts.. the higher the PIN to PAP... the longer the ball will go and hook.. more length lor.. haha..

how to measure PAP? check out youtube videos.. or go to the bowling alley.. throw one ball.. and see the oil ring closest to your thumbhole.. put the oil ring that is closest to your thumb hole parallel to the floor.. the top of the bowling ball is your PAP..

do some research.. go to the manufacturers website. usually there are two balls nowadays in the market.. reactive and plastic.. urethane balls are hard to find..

as a general guide.. those balls which are expensive are reactive balls which has a core.. unless you find the clear plastic ball that has some funny things inside like a love shape or a panda bear inside.. those are plastic balls.. other plastic balls are ebonite maxim.. brunswick t-zone..
