Alternative for boosted h3 neo, for a kid

[ttarc]

If he can keep one D09c one year, it is still interesting, at a financial point of view. But you say that Fastarc is durable, but this is how looks his one after 2,5 months of use ( and he doesn't always use it):

I would say that the FastArc is still usable. No significant damage or excessive wear in the main hitting area. Just to give some numbers: a ESN rubber like the FastArc was good for 30 to 60 hours (including reboosting) on my BH and looked much worse than this but this depends a lot on training intensity and how hard one hits.

I will see if this little hole on the top right is fixable... In addition of his weekly hours, he plays some day sessions during his school vacation, and go to tournaments or teams championships twice a month.

This hole is just an aesthetic issue nothing serious to worry about (good for training and tournaments) only some very pedantic umpires might have an issue with such a rubber.

I don't know the hardness of the sponge. I bought the "simple" H3 neo on TT11, assuming it's the "commercial" one. But there is no hardness info, not like provincial or national versions. Maybe it's random?

It used to be quite random (38° to 40° afair) but nowadays all H3 regardless which quality level should have a sticker on the package which indicates sponge hardness.
Don't know why TT11 still sells this old random stuff https://www.tabletennis11.com/other_eng/dhs-hurricane-3-neo but they also sell the 37° BH version https://www.tabletennis11.com/other_eng/dhs-hurricane-3-neo-soft
If your going to buy from Aliexpress shops like HWSports usually have all different hardnesses in all different quality levels e.g. https://it.aliexpress.com/item/1005005387832567.html for commercial H3s OS 38 to 41 and for the 37 BH version https://it.aliexpress.com/item/1005005439015436.html

For the boosting process, I removed the glue, I apply one layer but that seemed too thin at first. I waited 12h, applied another "normal" layer. Then a third thin layer after 12 or 24h, waited again, remove the TV remote from the rubber, and start to glue it but I saw that the size of the rubber changed. I put it in a wood press, which I don't need to do when I only glue a new rubber.

The size of the rubber should change. Sponge expands from the booster and the whole rubber domes/curls. Can be quite challenging to glue
