It has the "H3-like" dense sponge, and for me those rubbers, H3, Rxton9, DFVP, Battle 2, etc. are all in the same family, I mean if the top-sheet is not signif. different. I mean I can swap between them easily (assuming they have H40-H42 hardness). There are minor differences between them obviosly, but the difference to other "families" are much bigger for me.
I didn't try Artur China - when I saw people's experience here, I got scared. I only have Big Dipper H38 on Viscaria, for me the BD is a bit different rubber than the family above. Perhaps BD H40 black would feel different, but I didn't try.
My last sheets of H3 prov. BS felt kind of "ripped off"/"cheated" on me. The weight was lighter, when booster off felt more dead. And given the price was almost 2x as high, I felt it is not justified. I'm happy with Rxton9, if it didn't exist, I'd go for DFVP or Battle 2, not going back to H3 prov. BS.
The TDE has the proper sponge, like the family above, that is good. But the top-sheet felt very wrong to me on harder shots. It felt like I am wasting my energy. I gave it somebody. E.g. when I try to play with rubbers like Rakza Z or Golden Tango PS, or Bluegrip S1 on the FH, on those harder hits it feels like I am wasting energy because of the sponge. The TDE - the sponge was OK, that feeling was because of the top-sheet.
Obviously, Michael, these are just my personal feelings/judgments, we all have perhaps slightly different feelings... And I'm glad you like TDE.
Edit: Want to add that those personal feelings are not necessarily level-dependent. Some friends of mine - better players - are happy with rubbers like Bluegrip S1 on the FH.
