You got that right.I tried to switch to a higher vantage point further up off the cue so I could play in glasses rather than in contacts as well as take pressure off an injured back. Couldn't do it. It was more of a perception thing than a mechanics thing. For close shots, I could see them just fine, but a shot down table, say 6feet away was really difficult for me to see my shot line. How guys back in the day played shots with some distance to them from up high off the cue amazes me. When sighting low you can see how it all lines up, but up off it, it is really difficult. No wonder some of the top guys back then got lower on long shots and just played high up around the pack in 14.1 where the higher view of angles is actually an advantage.
Thats how I play.
And I learned how to play in the 60's watching the guys from back then.
