The blade is of its own class - agree. Provides you with a great and direct feel. Beautiful outer koto feel. There are a tons of reviews.
Of course no such thing as the best bh rubber. Depends on what you want to play, more control or more attacking game - see Zhan Jike (I consider Viscaria to be very similar) t64 or 05fx as some say, and Timo Boll - pure 05 (God knows what version now).
For us mortals [low amateur league player] who still love this direct feel, you have to compromise. For me 05 was uncontrollable, 64 or even 05fx too fast (could not block). Tried FX-S, didn't like it. My current EL-P seems nice but I bought it used (probably tuned before) and it was ok, not too bouncy. But I just got the new EL-P ... we'll see ... : )
Some like t80 as bh - but it still would be plenty fast I guess, specially with TB ALC.
