How does Xuperman play compared to DFVP?
This will be a bit unfair. The DFVP was kind of old, I had it on my spare blade, didn't use it much, and now, off-season, I decided to spend it, among others. The first one was C55, I mentioned it earlier. The DFVP was second one, it rel. quickly turned kind of greyish when I started playing with it, and at the end lost the grip a bit, esp. in slower shots. I was kind of closely watching its degradation, same as with the C55, and I'm pretty sure I removed it (both actually) at the right time for me ;-) - and both earlier than I expected... The Xuperman PP-X still has enough grip, it's joy to play again with it.
I remember you said you like DFVP, and I agree, for its price its a very good rubber, in a certain family of rubbers, like H3 BS, Rxton 9, Xuperman PP-X, B2 BS, Victas TDE. But while I like it, if I had to describe it in one word, I'd have to say: mediocre. In this family, the sponge response is kind of similar, but the top-sheet response of the DFVP feels for me, as I said, mediocre. It's not bad at all, don't misunderstand (there are other rubbers in the family, like STN, which I simply dislike), but you know some other rubbers can bring more. E.g. both the R9 and Xuperman have more elastic top-sheet, the R9's feels a bit thinner, than Xuperman's, but both nicely elastic. You need it to have the feeling of grabing the ball. The Xuperman is only 1g cut heavier than DFVP, so both are a bit heavier than e.g. H3 BS.
So, I'll now spend the Xuperman PP-X, and I'll enjoy it, but I already now that I won't use it again. It's not that easy to obtain it for me, in Europe, and I can't say I prefer it to R9, which is cheaper and easier to get. Now I have 2 half-spent R9 rubbers waiting in line, and then H3 Neo BS. I'll stay with one of those two. It will depend on whether or not I'll recognize that I enjoy H3 BS more than R9... Cheers.
