I can play pool at a fairly high level most of the time ( 2nd place in a 8- ball league consisting of about 60 players, most of which are beginners) . I do not use any type of aiming system or diamond system consciously that i know of. Am i missing out or are there good players that only rely on there feed-forward process and do not need aiming systems? i hear of these aiming systems a lot, i hope they are just a gimmick. Know of any pros that do not use aiming systems? i know there are other threads on this but i like to ask the question in my own words
