Hey Darion, ok so with the first question of course it depends on the player using it and their style, long fast backspin or even short backspin are both good against short pimples for sure. Sidespin topspin can sometimes be punched through with short pimples so perhaps not the best choice, sidespin backspin will be fine to use though. I would say like with playing any style or rubber the most important thing is variation and keeping the opponents guessing and making decisions. I will work similar to returns from normal rubbers but will come back at you with less spin than a normal rubber so you may need to add a bit more topspin to your follow up shots.
On the 2nd question there won’t be loads of spin on a serve from long pimples, they can generate light backspin but not a lot. So you can treat them almost like a float ball and topspin through them.
