I agree. Similar to how if you took away the leather tip im sure todays players wouldnt fare nearly as well as the old boys that were handy with a mace.
jokes aside, can you explain further why you believe the extension to be a “gimmick”? Several of the guys we all watch play with an extension full time. If the 64” cue only broke down into two pieces instead of three would that make it less gimmicky?
you are completely right though, proficiency with the rest declined right along with the rise of bar boxes, from what i can surmise. i cant use that thing at all, to the point where i dont even try any more.
