Personally I can't stand typing on Cherry reds as they are too light but some people like them so that's for you to decide, maybe QX2 reds are heavier anyway...
I have R1 Zealio housings (made by Gateron) with Krytox lubed Gateron clear stems in a board built around March 2016, I don't game but as of today F6 which I practically never use feels no smoother than A which is used often. I live in the UK so if it is oxidation due to humidity I wouldn't be affected.
