Thats what I thought of Z2. Heard it was a competitor to Dignics then I tried it. It's fighting against T05.
Much more power compared to tenergy. Less spin. It's more like glayzer 64 lol.
1. There is a big difference between commercial and provincial. But I do recommend the orange provincial.
2. I'd recommend getting the orange neo provincial. 39 degrees should be fine.
3. Rakza 7
Oh well for me Z2 is also bad in the short game. But not as much as tenergy as it's more spin sensitive.
I would be playing with V>15, if it were slightly harder. V>22 is an upgrade to it but not the same concept in usage.
Also it's price.
I've used both and tenergy 05 is better to me. Z2 doesn't create enough spin as it bounces off the racket too fast. The only time I'd say tenergy is uncontrollable is short game.
I'd rather use Dignics 05, V>15 or fastarc g-1.
