Tacky Rubber Loop Advice

from what i know: brush looping is when you use the topsheet mainly more than sponge.

The second diagram looks almost like you are doing an opening loop or looping a chopped ball.  I would hit it earlier at the peak and have the paddle close a lot more but I don't know the scale or the height of the net.

The strokes you use in the two diagrams look correct to me. My understanding of brush looping is when you close the angle of the racket as much as possible and swing along the same direction as the racket face, which is the way to maximize topspin. The opposite is hitting through the ball. The more you hit through, the less you are brushing.

What do you mean by the "r" shape? I'm unclear, and the video doesn't seem to clarify. I don't think you're supposed to change the face of the face of the racket at all throughout the swing, at least not during contact.

Heres what I do...

When I am using the loop kill, my racket is more open(maybe bigger than 50 degrees with horizontal)and once I feel that the ball "stops" on my rubber, I close my racket as I swing forward with my arm and rotate my waist(30 degrees with the horizontal). Finally, I snap my wrist to give the ball some more spin and speed.

where is the 1-5ms number from?

having EJ'd the living crap out of "high dwell" setups (soft outer plies, flexible faces/necks) and gone through a myriad of rubber at the same time including hard and slow chinese sponges, I can definitely vouch for "big swing against powerful incoming ball" is the only thing that seems to penetrate a hard chinese sponge and engages both top ply and flex. Certainly the subjective experience is that it creates a "longer feeling of the ball" especially during big counter drives.

and from network latency stuff (beware: online FPS gaming reference) i know from objective performance based results that my brain can easily register a 20-30ms difference (it affects timing and reflexes). And I'm sure that folks with better reflexes/faster neural pathways might be able to register smaller differences...


So here's another question - is the difference in dwelltime between an OFF+ carbon blade with a high(?) COR and fast rubber and a slow, flexible, soft ALL blade with harder sponge in fact more than than 20-30ms on certain strokes?

Because it certainly feels like it.

kinda...the issue is depicting the angle of the blade. i'm not disagreeing with your first picture (topspin) it's just the underspin/no-spin picture that i'm a bit iffy on.

as you can see in the following vid (even though i look stiff as a board) you get an idea of how to swing against topspin balls.



but against underspin balls, the swing will kind of look like the picture you just put up. maybe a bit more upward motion and less forward....

again, i am not an expert so please take this advice with a grain of salt.

I don't think anyone can adequately change the racket angle mid-stroke when the only part of the stroke that actually matters is the time during contact (dwell time) and dwell time only lasts something like 10ms.
