You dont need to listen to any recommendation^^
The difference here was that i gave the argument right away, while i had to seperatly ask for it. Many many user just say how to do things without any explanation at all, which is bothering me especially in cases that are far from being "common sense".
So to discuss your argument:
Brief explanation why the topsheet might get damaged from boosting.
Bubbling happens when the sponge gets seperated from the topsheet. So in detail - single pimples from the topsheet lose contact or their grip to the sponge. This can accure when the sponge gets expanded too hard, or afterwards when the you hit the ball. But the main reason stays the same.
To prevent that, the recommendation is to put a layer of glue between the sponge and the booster.
Correct me if i am wrong, but that just prevents partly the booster to get into the sponge and maybe slower. If that is the case, you can get the exact same result by applying thinner layers and/or more layers if needed, instead of dropping everything onto the sponge so you dont get a rubber tube instead of a slightly curled rubber.
And on top you have so many other issues with glueing first (as i have posted before), that i cant see the benefit here. At least not with the OS in my own experience and those from some other players. I mean in my case i boosted at least 5 Hurricanes (neo and non neo) with the layer and even way more (at least 15, though not all for myself^^) without the layer, and i have never accured any bubbling with these rubbers.
