I discovered yesterday that Big Dipper (Red 38°) comes pre-glued. I mean pre glued and not pre boosted (we already know that). In one corner of the sponge, there was a little bulge. And it was identical to the one we do when we start removing the glue from a rubber. I let it like that, glued like usual, and nothing weird to notice. But I wondered I someone else ha noticed that, and if I literally cold glue my BD right away after opening the seal.

what they do is, pre-boost and add a layer of glue to keep the boost in, then the film.
they did tell me can glue straight away, but I have experience (not with big dipper, but other yinhe) that the glue bond isn't strong, so I still advise to add glue on the rubber, maybe just 1 layer, and not the regular 2 or 3 layers.

Reviving this thread to ask R9 owners @Tony's Table Tennis @WingTT @mattlamperouge about how much to boost.

I bought the 40.5 version and right out of the package it's already clearly boosted. Never had a Chinese rubber as floppy and pretensioned as this (maybe Jupiter 3 comes close). I used the durometer on the sponge and it came to around 52d.

I ended up just putting a thin layer on top of the pre glue layer and it gave it a very mild curl. Remeasuring hardness and it's now 51d and I don't know if I want to go any lower than that.

Did you guys notice the pretension and floppiness right out of the package? Maybe the differences in experiences of people might be due to inconsistency in the amount of factory boost? Mine seems already on the high end.

Mine was testing sample (pre retail)
Mine didnt have any sealed packaging per se and it was reverse domed,
My first test was without booster, next session with booster. I first did 2 layers and monitored the effect.
I cant remember if I added a 3rd
This was early last year.

With booster, I always recommend to monitor the effect on how much and quickly it domes and the same for settling down.

If you are worried if yours is boosted already and still doming well, then just add 1 light layer and monitor it

The R9s i glued were firm but with good tension, the last one was for my partner, i added one layer of seamoon over the factory glue and i think it was enough, my partner likes it very much and can produce fast & spinny loops on viscaria (he was using commercial boosted 39 deg H3neo)
Mine is reboosted with 1 layer too after playing just with the factory boost for about a month. Then i needed to reglue so i wanted to test boost reaction and it plays even better.
Others i just glued from factory for lower level players and still plays really well.

I found the R9 pretty close to the Arthur China when I tried it. Unfortunately, my friend had boosted it, so it can't be a relevant comparison. It should have been tested unboosted.
Are you a strong fh looper?

For you these 2 rubbers were pretty similar? Any differences?

Thanks @mattlamperouge and @Tony's Table Tennis. I'll just stick with the one thin layer of Seamoon and see how it feels.

Decent approach. I did one bigger layer or 2-3 thinner.
In my further experience with it i found that too much booster made the ball harder to grip and therefore harder to give it a quality angle. Often times the throwangle was way too flat if i boosted too much. It didnt really get mushy but rebound was too quick. As if the rubber is a brick and couldnt grab the ball propperly.
And i would say so myself that i should be hitting hard enough 😅

LAC feels easier to access its speed.
Therefore i could easily make use of it on my bh.
R9 is harder to access (even boosted) but has higher topend speed, which would probably cause the rating by Loki.

The R9 I tested was boosted and very similar to my LAC unboosted. BUT, I tested it for 3 minutes, I found nothing interesting compared to my LAC, so I stopped the test. It felt similar, but maybe on some aspects, if I had investigated more thouroughly, I could have spotted some difference. Anyway, at first glance, I felt nothing that should make me switch from LAC to R9. LAC is perfect to me.

That's what happened with mine. I boosted normal 2 layers on it and it had a cracking sound and was super fast. It was really hard to play slow loops with it because of the low throwangle.

I played a tournament with it recently after 2month+ of boosting and it felt just right now. So yea, 1 layer seems to be enough.

After lightly boosting Rxton 9 and cutting it to my blade (surprisingly and worryingly light at 47g), I tried to pull the topsheet from the sponge of the cuttings.

This thing is impossible to separate. The bond is strong and will probably survive mulptile reboosting (which of course we should never do).

I rarely boost so I'm no expert but I put 2 layers of of Seamoon national White on the R9. It was pretty unusable for me unboosted. I should transfer the R9 to the blade I normally use for a proper test.

Why was it unusable?
The common reason - at the low end of hitting speeds it is less consistent for me and more work. I'm probably not the only one who have experienced the ball simply going into the net with hard Chinese rubbers due to the non linearity of response when not hitting hard. There is little forgiveness.

The LAC on the other hand, even the slower version I have now is absolutely linear and controllable at low hitting speed. Predictable even if it is not the fastest at the high end.

After using the R9 a few times now I think I mustve gotten a heavily boosted version of it. It's maybe the fastest and bounciest Chinese rubber I've used. Closer to Jupiter 3 38d than to anything else.

I've had to adjust my swing to a flatter trajectory and more angled blade otherwise the ball goes flying long. I was hoping for more grip and dwell time. Probably will go back to LAC after this.

Is it slower or faster or same as Jupiter 3?

I personally think Jupiter 3 is hard to top: tack, spin, hardness, speed, dwell time it does everything well.
