Balance determines how well your putter hits and holds a true line at greater distances (Dinged shots). Even off Ding-putters have to hit straight shots so imo Precision should be important to everone. Having said that, if you typically hit the ball 2-3Y from the pin then you'd be content with a high precision low balance putter.
Luckily, as you tier up most putters attributes increase across the board so sacrifice for one over the other/s (attributes) doesn't usually come into play. I'm not sure how far off you are from level 92 but imo pick up the 92 Ghost when you get there. You could always opt for the 86 Versa but it's meter is 1 full dot lower (92 Ghost only .5 dot) than your current with different increments too.
