i just bought a H3 #19sponge 2.0 for my FH. i feel that the throwing angle is very different from the prov' H3( it needs more from the back to front motion ). The topsheet also less tacky than prov' H3. Therefore i had to 'start everything from zero again to get used to the rubber
I like Palio HK 1997 wich is very similiar to japanese rubbers. The new HK 1997 Biotech is a bit to slow for me but spin is good. All Palio rubbers have a flat throw and it's recommended to use a blade with a softer touch.
after times of playing with H3 #19sponge 2.0. i found its weakness. it is when u a doing a blocking against top spin(heavy or light looping). the ball will then fly out of the table. i feel that the rubber is too bouncy for blocking and sometimes when u a countering yor opponent's looping attacks, u will also find difficulties to 'press'(loop) the ball to the table. the ball simply strike out of the table
