I have the pg 7 right now from dhs. And better as in speed and control
Speed and control is like 2 totally contradicting things
Faster the equipment = more difficult to control
Slower the equipment = more easy to control etc
In the speed glue era, thinner sponge will equal more control
In Chinese coaching, thinner sponge will be better for beginners
In ESN rubbers, thinner sponge will allow the ball to hit the blade too quickly - and some people don't like this.
IMO, you are using super fast equipment, maybe you should slow things down a bit if you are struggling with control
