hahahaa... to be frank, i personally dun follow such system when it comes to sparing... had tried and failed many times... at the end of the day, i think it's still better to come up with your own system which is most comfortable and consistent to you as the bowler.
like for me, when it comes to sparing pin 7 and 10, the third arrow is my target. my standing position never change. i prefer changing the target.
just my personal preference lah... but if you think the sparing system like the 3-6-9 works for you, please... follow it religiously.
but hey... thanks for sharing... you dun tok much here, so well.... hehehe... good to see you finally 'opening' up.
