Hi, the Voltric 80 is much stiffer than your current racket and needs more technique to play injury free. Would recommend not using it if youre still a beginner. Oh and you need to warm up your shoulder properly so that doesnt happen in the near future.
Other than that, I have not tested the other racket (Victor).
I would say 24lbs is a good tension. Maybe you could try Li Ning N63 string for the best sound I have ever heard (disclaimer: at 32lbs).
Enjoy!!

No worries, it will come with time. I started my journey 15 years ago with 19lbs and now, after a long, long time of training I am still not comfortable with 30x32... so stay patient and keep training mate!
