I think I accidentally my spin.
I took out another not so crappy premade but still premade I have (The pimple composition is not rubbish and it's not dead, so it spins a little nicer) and started swinging as hard as I can, trying to vary my blade angle to produce different contact.
Carl said my blade angle control is bad, so I decided to find out my habits. I found out that I actually very slightly OPEN the blade angle before contact. Most likely because I've been playing with dead shit rubber for so long.
I tried keeping the blade angle the same by force, and it actually made a slight difference. Now the ball rolls back to the wall and touches it after hitting it, although not as heavily as I'd like. A good rubber would probably give me the spin I want with my current touch.
Here's the weird part. I tried to swing in as unchanging a plane I can, producing as pure topspin as I can and grazing as slightly as I can while swinging as hard as I can. I used a bent arm stroke and whipped the wrist forward at nearly painful speed, if I hadn't been relaxed.
The ball hit the endline of the table, hit the wall, bounced off then decelerated halfway to the table, launched itself into the wall at a ridiculous speed when it hit the ground and got stuck in the corner near the steps, while it rolled up and down the wall, making a scraping sound. It didn't even bounce a lot after it slowed down a bit, it just spun itself to a stop.
I thought what the hell, I've only seen spin so heavy in CNT training videos when they miss shots and it goes into the soft barrier. Had to be a fluke.
I missed a few then landed another one like that. I tried for some time but couldn't replicate it for the life of me. So it was a fluke, but I didn't believe that was even possible with my equipment.
I don't think I will ever get so good to be able to replicate that on even 10% of my shots with this equipment, but it was ridiculous. Easily 10x the spin I normally put on the ball. The contact was very, very fast but I could feel a slight resistance when I hit the ball, so it probably barely grabbed on. The sound was not a crack either.
I really don't think that I could get that kind of spin even with good equipment using my normal slower strokes, so I did something very right. I'll keep trying to replicate it, then try to reproduce it regularly when I finally get my hands on good equipment.
I can produce a grazing contact now and choose when I want a cracking slap and a soft contact when swinging very hard, and there's okay spin too, but I'd really like to be able to always get this kind of spin.
