Thanks for the ranking, it was very useful, despite the difficulty that exists to objectively measure many of the characteristics ... everything could be objectively tested but it would maybe require complex machinery, slow cameras, etc., and a lot of time and money.
In my personal experience, I have played on BH with Big Dipper (BH), Sieger Pk50 (BH), Rakza Z (FH and BH) and Dignics 09 C (FH and BH), also with Hurricane 8 soft on my BH. Those are the ones I've played the longest. I have also tested a short time: yasaka rising dragon, shining dragon, hovering dragon, thunder dragon, rakza X. Of all these, rising seemed the best for the FH and I understand that it is quite successful in Japan, but maybe I'm wrong because not I understand Japanese, although it is well raked on tt-japan dot net. Then, the one I liked the most of those for the backhand is hovering dragon, fast, less sticky than Rakza Z and with a lower shooting angle ... but very good rubber. Shining dragon seemed too soft, with little power, and hovering dragon I liked more, but still too soft ... Rakza X is good too for BH.
Of the ones I played the longest, in the end the best rubber for my BH was Rakza Z because it allowed me to kill the effect of the sliced balls, being able to attack them with top and opening the offensive exchange or scoring winners. Rakza Z can be very violent on a Viscaria, and is also powerful on an Acoustic LG.
I use Victas Triple Double Extra in the FH because it seemed very hard for the BH, but I know that Koki Niwa uses it in the BH (of course, he is a professional and hits him harder than me); I love this rubber too, I find it similar to a boosted national H3 (the best one, but very expensive because it last just 1 month or so), and to a Yinhe Jupiter 3 tour or a DPR Korea team: all those rubbers are really similar ... maybe Victas TDE has a slightly higher throw angle than them ? I don't know, but the feeling is beautiful.
What surprises me a lot about the Victas TDE is that my friends who do not play with Chinese rubbers, when they have tried it, they have not had as much difficulty as with the h3, it is seen that the angle of fire is not that low, although it is more lower than that of rakza Z.
I also love Sieger PK50 for the BH but I think it is a faster tire and it is harder for me to lift slice.
H8 soft red is less reactive but very precise, it has given me good satisfaction.
