What is this targeting concept and how does it work? I was shown the concept, based on a starting point of placing my left foot on the 20 board. Question: how does the targeting change if my left foot starts on board 12?

I was, still confused.....I hook to the left side pins for spares. Hooking to the left, I just watch my ball motion and where the oil is and ends. I move 369, but I "spot" bowl for the spares, aim to the right of the pin(s) a few boards.  if I had to stand @ 12 and aim at the second arrow like I was told, I'll pull my shot. I feel like I'm on a tight rope..

Even the USBC Video on this, the girl wasn't even hitting the second arrow.....

I use that system for youth bowlers that are just starting out as a guideline.

Lots of awesome links right there. I prefer the KISS method to picking up spares though.

In the first link that I posted above, at the bottom of that page are links to other spare systems like the KISS.

Thanks! I'll share this with some people who have been asking for help with shooting spares.

I just noticed a typo in the KISS system chart.  The last pin they have 7 but it should be 10. 

C'mon, Bullred; why is it BS? Do you really want to return to the site just to be another in the long line of flamethrowers? We already have far too many people who love to jump people for everything that they post!

Personally, I agree with you. I don't need to follow a system. Through experience, I have learned where I like to stand, how I like to align myself, and what type of release I like to use to shoot my spares. That works for me (well, most of the time anyhow    Nevertheless, that doesn't mean it's wrong for people to look for systems like these if that's what they think is going to help them.

Remember, not everyone on this site is an above-average bowlers. There are plenty of beginners and/or lower-level guys and gals around here. Some of them just grab the ball and go without even looking to see where they're standing or how they're aligned. As such, if following 3-6-9 or some other system works for them, what's wrong with that?

It's nice to have you back, but lighten up, man!
