Need to update my initial post, but it's hard since I use a different blade, which means a different weight, balance, blade face shape, every wood ply is different, only the outer ALC is "the same".
My first assessment was with a Xiom Ice Cream AZX Pro blade, but I would like to revisit what a blade change can do on the ranking.
I would say the Xiom Ice Cream AZX Pro is like a Viscaria in a W968 form. It has Viscaria properties but the balance and some comfort of W968 so I think it's a very worthy mass-manufactured blade. Much faster and the speed and quality comes up much better than on Viscaria, and it's faster than W968 by a lot but the quality doesn't manifest so nautrally.
I tried many of the rubbers on my Taiwania blade which is a miracle but also I tried some on Stiga Inspira plus and Mizutani ZLC, Lin Gauyuan's Guanjian ALC, FZD SALC. Mostly these were my test subjects.
-1, Pinyi Cuifeng, it has the most potential on normal production blades. It has the speed the hardness the topsheet grip and stick and snap, I think it is probably the most safe rubber. If you use it on a very hard blade it will be difficult to use but the potential is there. Weight is better than german rubbers and durability is excellent.
-2, Quanshibao F1, very easy to use, very much like I said a half way DE-boosted H3BS. But I still think that is quite a good rubber to have. Weight is very good, stick is low but the topsheet is very user friendly. This is a comfort rubber and if you have difficult blade I would use this rubber on it.
-3, Sanwei National Target, by this I mean the new Sanwei national target with blue sponge. Not the black or purple or G40 or player etc. The normal one. Usually this rubber feel like it has a low arc, the speed is OK but not great, the spin is pretty good, it feels like it needs something extra. Maybe that extra is boosting or a faster or a blade with more curve and I feel that too. I didn't wanna boost so I first put it on the Mizutani ZLC and it felt pretty darn good, the speed was acceptable, arc was acceptable still it felt a bit lacking.
I glued it on the Taiwania and god damn, this rubber is amazing. Speed is more than plenty, arc is so good I need to hit flatter to not over arc the table which incidentally improves the speed even more. Amazing rubber with that blade. On other blades for me the best one so far was Mizutani ZLC and in the past Cybershape Carbon. But with Taiwania it's so much better that it's a totally different league. Weight is amazing at 48-49g and durability and stick is better than H3...
-4, Loki Rxton 7, it's just great. I would say it's like a sticky and a bit harder T05. It has a very decent catapult, the topsheet quality is quite good, the sponge is also quite good. I really don't see any problem with this rubber, I think it's a very friendly and easy to use rubber that everyone should try. The 40 degree version is totally usable for BH.
I talk about a harder and stick T05, maybe I should say it's a poor man's Tibhar K3. It works on most blades, it's not picky.
-5, 729 Battle 3 Tiger 4, damn this rubber is weird. First I used it on my Xiom Ice Cream AZX Pro on FH and it was interesting! A bit slow but every ball went on the table despite whatever Xu Xin bullshit I tried and it had amazing spin. My opponents couldn't block it on the table. It is a bit heavy at 53-54g cut,, but it performs amazing.
After the Xiom blade when I came back to my country I went on an amateaur national competition and I glued it on Taiwania blade and it felt just great, spin amazing, speed plenty, but heavy. Actually my BH with a slightly more heavy and harder Glayzer was more of an issue but still I won the competion only with two 3-1 matches, the rest was 3-0. Solid rubber, but heavy, no blue sponge.
-6, H3N OS 37, actually on the Taiwania blade on BH side totally de-boosted it felt quite right. Since I tried it my brain is thinking that something with a bit more speed would be amazing with the H3 tophseet, so the H3-50 is now in my mind. When I flipped it to my FH it still felt quite amazing, so the Taiwania blade has some extra kick for these rubbers.
-7, Battle 3 Purple lightning, as much as I anticipated this rubber it bit me in the ass. Maybe I got a bad sheet or I don't know what happened. It was too soft, the topsheet was not grippy enough, I had many issues. I guess I need to buy the 41.5 special edition to get a good sheet. But even with all it's problems it was fast, spinny and light. Just had some issues.
On a very hard wood outer ply wood I think the Sanwei Target National will shine, and by this I mean some rosewood or similar blades. On more conventional like I try to describe.
