“Just tested JNA 1.0 mm on BTY Innershield blade with V>22 on FH.
Compared to YAP 1.3 mm with V>15 Extra on FH in my opinion there is more control and feeling in the defensive play (a bit slower). In the offensive game both rubbers are very similar. JNA seems to have a little more of a disruptive effect. Very good Anti Spin rubber just like YAP. I recommend both :-)”
