What I've noticed after trying out the "regular ezone" versus the "tour ezone"

Tour:

Pro:

Excellent depth, excellent stability on "blocking back balls", can easily push balls back in at a decent depth, if you have time to setup and really fully swing at it- easily pushes players back, consistent penetration

Con:

Extremely taxing. Towards a hard set, you block balls back, start dinking stuff in, and stop taking big swipes at it. While you can "push balls back"- you either have to take a full swipe at things or block things. There is no "in between mode."

Ezone normal:

Pro:

Can consistently swing at the bull full pace without any drop off, more manueravable. You can get away with being late preps, and or having an in between swing. Can play a full 2 hours.

Cons:

More service/baseline depth- not as penetrating, gets punished when trying to block balls back as less stable. Not as satisfying in comparison to Tour when you take a full swing at stuff. You have to really swing all in to get it to not get attacked. If you don't it lands at service line and you get hammered. So I guess its promoting me to use the full kinetic chain?

Overall- I like the tour version more in the first 20-30 minutes- but after 30 minutes...I get really tired. I feel like my average ball is better with the ezone normal and I can keep hitting well after.

Is there any reason why I should entertain the tour version over the normal one? I'm leaning towards the normal one. How do I get stronger to wield tour versions?
