Hi all

I recall when I had a brief go with Rakza 7, it struck me as one of the most unusual inverted rubbers I'd ever used...mostly because it was so incredibly spin insensitive. It was a breeze returning heavy topspin loops that normally I would have had to really put a lot of effort into to keep down.

I heard Rakza 9 was a faster version of 7. Just wondering if it is also just as spin insensitive.

Thanks!
PK

Hi PK. I played R7 for over a season and changed to R9 last year, so between them they are the only FH rubbers I have used for around 3 years. I would say that R9 is LESS sensitive to spin than R7, a little faster and a little less spinny. Distinctly lower throw/trajectory which I really like once adjusted.

It doesn't makle sense to me that a rubber can generate a good spin of it's own and be insensistve to incoming spin.
A high level of grip is needed to create a high levl of spin and that is sensitive to incoming spin for the same reason.

I think it is somewhat more complicated than that. On many rubbers you need to engage the sponge to produce the spin, and on softer shots or blocks they are less sensitive.

In which case Rakza wouldn't be good for brush-looping?

In general I would say that brush looping is not a Tensor strong point. Not to say you can't though .....

Rakza 7 a nd rakza 7 soft (actual my rubbers) are sensitive to spin like all other rubbers i have tried (DHS Huricane neo 3 , Andro rasant powergrip, buterfly 80FX ,palio cj8000 .... )
I do not see any point in this ... difference is when you hit hard and the sponge is activated , then you can see a diference depending of the softnes of the spongebest goes out the buterfly fx80.

Just for posterity sake, Rakza7 and Rakza9 are moderately spin sensitive compared to other equivalent Tensor rubbers that are highly sensitive.

Rakza7 is the spinniest while Rakza9 is the fastest.

Rakza7 is medium-high throw while Rakza9 is low throw.

Very very grippy topsheet on both and very very durable as well.

Yes it might not be intuitive how a rubber can be very spinny, yet not so sensitive to incoming spin. When you think about it though, a loop 'brushes' the ball at a very different angle and impact speed compared to a block (or any other stroke), so it's not surprising that the interaction of the topsheet and spin can give different effects for different rubbers.

Would this spin insensitivity extend to serve returns? I think that is where most people would find it of use... In any case I suspect it's a matter of nuance rather than a huge difference, as it usually is when comparing rubbers.

A few rubbers that I have found to be very insensitive to spin.

Donic Acuda S1 and Joola Energy Extra Green Power.

I use the Joola Energy Extra on the forehand with a Gergely 21 blade.

Awesome for flat hits against slow no spin balls and can also hit moderate paced heavy topspin balls.

It's so fast with a click feeling. The most underrated rubber on the market.

It's as fast as my black Tenergy 64 that I use on the backhand.

Downside - it's crap for brush looping.
