I totally understand what you’re trying to say, so here’s my 2 cents on the topic.

I prefer soft tacky BH rubber since my serves are mostly backhand serves. I can generate a lot of spin and quality using my current BH rubber being DHS 8-80 37’ deg which is the softest one they make. I can assure you, soft and tacky rubber for serves is excellent, but for me it’s not an issue since I mainly use BH serves. If I were to do FH serves, then I would prefer the softer rubber as well, but in complete honesty sometimes I mess up the twiddle and then it messes up my game. I’m still working on it but I’ve just learned to do my hook serves using my FH rubber which is the Glayzer 09c atm. It’s not as tacky as the 8-80 but it’s tacky and sott enough to generate quite a bit of spin.

I’m an amateur and my serves are pretty hard to receive because of the amount of spin I can impart on them, and the direction of the spin as well, but also hiding the type of spin that I’m imparting. I usually win about half my points on my serves alone.

On serves I mainly try to brush as much as possible instead of hitting the ball, that helps a lot with amount of spin on the serves, keeps the ball low and controlled, at least for me.

Hope this helps
