What other still in production hybrids have you tried and how do you compare aside G09c/D09c?
I have tried mainly ESN hybrids (Tibhar K3, MK, Andro r 53, Xiom china Guang, Sieger PK 50, Rakza Z nad Donic Bluestar A1 and A3, to name a few). There were not convincing for me, but of course it is a matter of personal preference.
As for G09 and D09c - D09 I have tried both in 1.9. and 2.1 thickness, this is superior and premium rubber, but one must be able to generate own power, esp on FH, which I cannot do. D09c is spinnier, faster, but has higher arc and thus - at least for me - is less controlable, which a key at my level. I simply think D09c in far beyond my level of play I cannot use it full potential.
G09c is more friendly, but much slower and IMO not so spinny as BTF rating shows (its surely not above tenergy). Victas 15 S seems more versatile and safer than G09, with comparable spin but less control that Victas I would say. D09c is different beast, meant for pro players, some people try to compare V15 sticky to D09c, but I think they are different rubbers. V15 sticky is bit slower, has lower arc and spin too, but is versatile and predictable. I think it requires less effort than d09 to generate power and is least 8/10 in every department.
The best way is to try personally as your impressions may be other then mine. All ESN semi tacky hybrids seem be more/less all the same (except rakza z which was visibly slower than other ESn Hybrids), Victas V15 S seems different, you have the sense of power when needed, good feel and grip (nice click at contact) and good (thou not outstanding) spin. Control seems laso higher than other ESN hybrids.
That ia all I can say for now (note that my comparison is generally built on 2 ,5 years exp of Fastarc G1, which may not good base for comparison overall).
Hope it helps
