Libra CH120RF really hasn't aged well. I personally never experimented with it much, but if you look at the stats on the original testing that was done, it only had a 60% win percentage against MF Libra C145WB, so of course it will be useless against RS or any other rubber-based Defense Bottom.
What should be tested now is its effectiveness against Attack and Stamina combos. Honestly though, I think it is time that people moved on. There are countless other options out there that are likely much better.
