I really like Tenergy 05 on my Apolonia ZLC and Mizutani ZLC blades, but it's price is high, and it's initial great play characteristics change quite fast (after 80-100 hours of play it' already noticiable), so I tried to find a cheaper alternative... for FH I somehow migrated to Rasanter R50, but on BH I couldn't find anything to change tenergy 05... until I tried O7A rubber, it's a bit stiffer than 05, but overall for me they kinda alike to the point that I switch to O7A from 05 entirelly, I even changed Rasanter R50 on FH to O7A... But, I still think Tenergy 05 is better, the reason is overall balance of key parameters (speed, spin, etc...) and a few cons of O7A... The main issues for me in O7A is the lack of power and incoming spin sensitivity. But maybe problem with lack of power is because 2.0 thickness of the sponge in O7A I use, already ordered one rubber with max thickness, waiting for it to arrive, hope it solve the issue, at least at FH... Still kinda bugs me the problem of incoming spin, having issues with playing topspin on incoming backspin, the reason is with O7A I have to consider the amount of backspin and do it quite precisely, or else ball could go to the net or over the table easily... So, not beginner level rubber at all, but I like this rubber, so will try to struggle with it some more, but I'm not entirely sure my level will be enough to eventually use this rubber freely...
P.S. Originally the price to O7A is close to Tenergy series, so IMO if you don't have a big discount on O7A it's better to go with Tenergy or search something cheaper...
