Guys I have some questions here. Please do allow me to ask. Sry if it's off topic.
Off topic, LOL
Wait for my reply to Lodro...
1. I plan on buying h3 neo prov bs either getting 39 or 40 degree since it's affordable for me(first time h3 user or even any chinese rubber alike). I'll boost it with haifu seamoon. As I've read, boosting makes the sponge softer so should i get 40 over 39? cuz I'm worried boosting 39 degree will casue it to be like excessively soft. Or as a newbie h3 user, is 39 already enough or like a good start. Any suggestions on that please.
It all depends on your level and on how hard you hit, well, on the balance of it. For example, for my beginner friend I bought H37 (on a inner-force type blade, Vodak Horejsi APC). I expect he will use harder and harder rubbers on the FH as he progresses (if he stays with those type of rubbers). On the BH, I don't know, H37 is fine for me. So if you are 1st time user of chinese tacky rubber, then depending on your level, I'd go for H37, H38 or H39. Of course you want BS, so only H39 fulfills. I just don't want you to be disappointed.
Maybe you saw the hardness translation table in another recent thread. I posted it, I don't remember who I have it from, but I think it was zeio, who posted it on TTD. Anyway, if you like hardness 54 on the FH, go for H40, if 52 or less, go for H39. Due to the deadness, it feels subjectively harder, that's why I used number 54 and 52 (the higher ones of the ranges).
2. Should I add a layer/layers of glue on sponge before boosting or should i apply the booster directly without any additional glue layers prior. I've seen the two sides so what's the difference between applying glue layers first or not i.e only booster.
what's the better way among two for someone who wants to use the rubber for as long as possible.
I've read this article :
https://blog.tabletennis11.com/to-boost-or-not-to-boost
In boosting, I believe it is important to achieve uniform/even amount of the booster over the whole rubber. You do this by applying thin amount, wait until absorbed like 12 or 24 hours. Even if you spread properly, you'll see islands of more booster after a while, you can try to correct/spread it. Layers - 2x is enough for start, you'll see how it domes. You can use 3x next time. Whether glue first or booster first, opinions differ. I respect both, I personally do booster on sponge, glue later, but the other way is fine, tried it too.
3.does using protective flim (something like xiom o-foil) helps to maintain the rubber tackiness i mean is it effective?
Thanks beforehand to my fellow friends
Yes, I believe so. There are different protective sheets. And I'm using the whiteish plastic sheet that was delivered with Donic Bluegrips, it has the right firmness. I remove the air with fingers when I place the sheet on it, after I clean the rubbers, which I do usually after each training. Still, the durability of the recent H3 prov BS is less than durability of H3 red H37, don't know why.
