How ESN makes sponge

GOLDEN OIL BEGETS GOLDEN PRICE....

Why all the rubbers that coming out for sale with [size=+4]"national"label are priced so cosmic-high? Insane money at any rate..

I have now got an answer from a fellow of mine, he got it directly from an asian official while in Kazan on his umpiring duty. Curious tail to hear.   

-- All the National rubber versions are supposed to be soaked at factory stage with a natural oil compound extracted from a marine blue plant, as much costly as a pure gold. The treatment would take some 20mL of the oil product per sponge sheet.
   Taobao does have this oil on offer. Insane prices....

The only advantage one gets with the "golden oil" --it would work somewhat longer than baby oil. Nothing else .
Overprised product anyway.

If you swing harder than that, there are plenty of harder esn sponges. Some are much harder than even the 40+ degree dhs and the still outspin the dhs rubber everywhere. I use dhs rubber but im no fool and I do realise its nothing special and no better than the sheets of 729 I was using in 1984. The rest of the world has moved on. I liked 1984, Im used to it but I would never be so stupid to say dhs make high performance rubbers because they just dont

Bluebucket I agree with what you say, use whatever feels good, some players actually play better with a $15.00 rubber, they tend not to overhit the ball.

Rasant Turbo, harder topsheet harder sponge. more spin is you can use it properly.
