Boosters, what to choose?

[Haito]

The R9 has been boosted with yellow or black ?

Kailin. I do not have opened bottle of nat yellow. The nat black I borrowed from a friend.

Tell me if you boost your next sheet of R9, with which booster, and your reaction/feeling afterward please. I have gathered more infos on the Jiechie on french forum, and people (multiple) share the experience of "I did not felt the need of reboost before 3 months". I am checking if the effect is strong or not, how many layers etc...

It seems there are two Jiechi boosters: one black & one green, so we need to know if there are differences?

Well, to me the dynamism is felt for let's say 2 weeks. But after that you still get some sort of tension induced by the glue. When you glue a curled rubber, the top sheet gets extended, you see the pimple, and you kinda keep that "tension" as long as you keep the racket glued. Additionally the sponge feels "softer" easier to activate but not dynamic like the first 2 weeks. To me, after 2 months you lose all that soft and tension feel. No measure there but the feel. The dead feel of H3 comes back after 1.5 month/2 month. But the dynamism of the booster last 2/3weeks.

So the 4 months is perhaps this non dead feeling.
The 20% more elasticity is probably marketing garbage. To me it seems very unlikely unless you apply tons of booster. But the sponge gets damaged at this point.

Sure, the tension effect should be active for a good while, even if the rubber's not at all faster.

I can never get the edges to stay on if I glue curled, though.
