Hole reinforcers only work if the balls are all the same size... Same as the magic rack in that if the balls end up getting out of spec by more than a little bit you won't have a frozen rack... Hole reinforcers will allow you to move them closer to the center ball but now you have to have the right ball in the right hole which means you are having to pattern rack to get it to work....
Accu-Rack Templates work on the balls even when they are worn... That's my sales plug for today... followed up with.... I'll take a good rack on a template every day over having to deal with the inconsistencies of a wooden triangle, tapped spots on the table, and the additional wear a template prevents in the rack area....
Not to mention the fact that some shady individuals will never give you a good rack if you leave them with the triangle...
1st Funniest thing I have seen so far was a rack mechanic trying to shit rack using one of my templates... He racked 12 times trying to split the balls the whole time swearing it wouldn't freeze them... I was concerned and was walking over to ask him if they were having an issue when I heard him tell the guy who was with him he couldn't keep his opponent from making a ball because he couldn't get any gaps....
2nd funniest thing was a guy who swore he made more balls without the 10ball template and it was hurting his break.. He was counting on the gaps in the rack to randomly let a ball fall when he had no clue as to how to even break 10ball.. Got the same thing from a girl who didn't even have a break.. Granted if you know what gaps can help you it's one thing but when you think any gap is gonna help you are misinformed and a few bricks shy of a load.....
Since the balls spread out properly using a template the only ball in the rack area is usually the key ball... The odds of the template interfering with a rolling ball that was going to maybe freeze up or block a pocket are way less than 1%... I've been making and using templates for 2+ years now and while I will admit the path of a ball sometimes is changed slightly I have yet to see a case where I thought it may have impacted the actual outcome of the break to make it substantially harder or easier.....
My last comment is that a hole re-enforcer will alter a slow rolling ball just like a divot where the balls have been tapped in will... Anything on the surface or done to the surface is going to have an effect. It just comes down to the fact that having a good rack every time is far outweighs the few times you see a rolling ball alter course by a small amount....
Food for thought,
