ESP Zones are great for hyzer putts when that is your natural body motion and you have no confidence in your putting. Recently I have been putting to the right of the basket. No matter how hard I try to aim for the left, something within my mind still sends it right. Hyzering helps a little, the Zone helps even more. Also, since it has so little glide once it loses power, you can muscle a putt towards the basket and not fear too much of an overshoot.
I still prefer my Ridges and Summits for longer putts and when I feel confident, but when that confidence level is gone, that is why I carry at least one ESP Zone in my bag.
Side note, Zones are decent for approaching because they are very predictable even into the wind, but I would never use them for driving. Try as I might, I could not break 260 with these (not counting bounces or skips). While I prefer finesse mids, I can get Ridges and Foci (plural Focus) to 300.
