I replaced my rubbers with exactly the same model, and it took me 2 weeks to get used to them!
I imagine with a new equipment it would take me a month or two to get used to it and play well.
I have two identical setup. I play with both each week, to wear them equally. I don't need to do this, but it's fun to know that if something happen i can switch and keep playing like nothing happened.
Any setup will do. I played with G1 and they are really good.
The idea with the rozena is you can switch to the tenergy serie as you progress, if you want. But the G1 is a tamed down T05. Really good and last a long time.
Your pick really.
Get a Petr Korbel with two rozena, stop worrying and start hitting. Change in a year or two if you really want.
Table tennis is a control game, and unless you have ton of it it just make things harder and painfull.
If you can't constantly open-up on both wings, pull crazy shots when out of...
I've been playing for 1 1/2 year with a Korbel and Mantra Pro M. I just don't care anymore about rubbers and blades. At my level it's not the equipment it's the skill that win the game. Some peoples need an EJ phase to understand that. :)
You can try Universal Parcel Tracking, it will scan multiple courrier and you will be able to track with the appropriate courrier. You will know who have your package.
I use water based glue on rubber (copydex), and elmers rubber cement on blade. I find the bond strength just right.
I have many limba blades (korbel, fextra 7) and never had splintering problems. I don't seal my blades.
