Spin makes the ball's trajectory curve due the Magnus effect. More spin (for the same initial velocity) means a sharper curvature, and a sharper curvature (for the same initial velocity) means more spin -- that is unavoidable physics.
So what's the point? If you can't make your shot follow a curved trajectory, then it means you're not putting much spin on the ball. That's not necessarily a bad thing: a less spinny shot can be harder to return, especially if the opponent is surprised. But it is harder to be consistent.
My hunch is that many amateurs think they're getting more spin out of H3 than they actually are, maybe because they've read a bunch of online posts about how spinny H3 is. In order to get great spin out of H3, you need to boost it well and have efficient technique. If you have both of those things, you will have no trouble producing high-arcing shots with H3. Without both of those things, H3 can still be a useful rubber because it's slow and not sensitive to spin, so it's good in serve/receive and for hitting through spinny shots. But its offensive spin capabilities will not be that great.
I think you're a little confused here? Different rubbers have different "throw angles". There's plenty of charts online from rubber manufactures that show this. You can even feel this yourself when you use different rubbers. If you use one rubber on tuesday, then switch to another rubber on thursday, and you notice a difference in the throw angle, it's not because your technique changed in two days and you produced more or less spin, its because the rubber has a different property.
I used orange sponge for over a year and now i'm using blue sponge. the throw angle is definitely lower but it's also spinner+ faster than the orange sponge.
I believe you are conflating spin effect with throw angle effect. Throw angle has more to do with the initial launch trajectory of the ball (IE, which direction the ball leaves the racket face at the moment of contact). This throw angle is influenced by dwell time, sponge deformation and rubber grip.
We know the blue sponge is more dense, and harder than the orange sponge. even at the same degree (say 40). Even at high swing speeds, the blue sponge will have less dwell time than the orange sponge due to its harder nature. However, it will also rebound faster (which creates more spin than the orange sponge). the result is going to be a lower throw angle but a spinnier ball.
All of this happens even before the magnus effect can start to take place. once the ball has been released from the rubber, at its throw angle, then based on how much spin the ball has, magnus effect will take place. So what does a lower trajectory high spin magnus effect look like? the ball traveling flatter for longer, and then a sharper dip at the end. This all lines up with physics just properly when you consider the initial lower throw angle...it means less vertical distance for the magnus effect to act upon.
U do have to get used to it. But once you do the reward is super satisfying.
agreed. i'm definitely making some better shots when its on!
