new rubbers?

hello hello, my premade racket got stolen from the mailbox so now i'm considering just ordering new aliexpress rubbers for my 25 year old beginners blade (joola balance) instead.

budget is kinda tight so i want the squeeze the 'best' out of my 10-20€. i'm fine with less speed since i'm just catching up right now and dont intend to spend a lot anyways.

i have my sights on 2x 868 for 8.90€ but then theres also mercury 2, corbor, tornado v5 and all the others or should i get different rubber for backhand etc etc i'm sure you can relate.

i originally setteled for a premade just so i can get something quick, but i kind of can play with any shit blade so why not be patient and diy it.

i play with different blade each time (more or less) so main thing i want is my own so i can dial in for more than a session.
