I came to my friend house and did this 3 frozen balls. I dont think his poclet are gaffed. He uses double thick shims and the end ball just drops.
Unless I do a straight in shot from 1.1/2 diamond OB-Pocket distance with my CB down 7 diamonds away with a long draw shot. If I tried to draw back then the OB would rattle with the most miniscules errors of unintentional sidespins.
The side pockets my friend said is usually a mistake of when people didnt use Lazer to level the rails. Then it will stick out or worse, 1 rail would be offset from the rest by a couple mm.
He agrees that if we double shimming the way he does, there is a dead spot at the corner ends which is about 3/16" (1/2cm) away from the pocket opening. Therefore, trickshots like those that need a good rebounce from corners as shown on tiktok and so on, are mostly uncontrollable. However, in normal play, most people dont ever encounter the scenarios to rely on the end rails corners for deflections, and most people do not rely on it. Possibly only for 5% of the shots where a kick or bank is needed from within 1/2 diamond OB/CB/Pocket
If we talk into account that a purposefully good tables that needs subrail extensions with wood, then it is the best way to rebuild and reconditioning a table, most time consuming and expensive especially when looking for mechanic. But to him as a handy man, it is an easy job, just time consuming and he thinks it isnt neccessary to involve all that expenses of cloths and rubbers. Because a table that isnt fair have many other weakness that can easily outmaneuvering the 3/16" deadspot from pocket corners. Like a slight unleveled, cloth indents, cloths with holes and rips...etc. Rails that are not properly leveled to line up straight...etc
He definitely agrees that doing double shims on a table will improve the accuracy and precisions in making shots. Therefore, it is fine for players to practice at home table with just that and avoid incurring further expenses
I am learning the tables and it mechanics in relations to the game itself. Of course I am easily confused by different claims and statements. But so far, this is what I have been cleared about
