Hey guys! I've been lurking GH for close to a year now, but finally decided to join and make it official! I have a question. Has anyone tried swapping their MX Brown springs for 62g ones? I've looked for answers around the web and forums, but haven't had much luck. I was originally thinking about throwing some Gateron Blacks into my QFR, but then I had the idea of changing the springs to 62g gold plated springs and lubing the switches. I'm sure there have been at least a few people out there that have done this, but I haven't been able to find any reviews or comments about it. What are your thoughts on this? I would rather mod my existing switches to make my keyboard that much more "mine", rather than just buying some switches anyone could buy. Thanks in advance guys! I'll post pictures of my white QFR in the other thread soon! Cheers! 
There's very little difference in strength between the stock Brown springs and 62g "Korean" springs, they're only a little stronger. The point of using 62g springs in Clears is to make them lighter, enhancing the tactility, while still having a strong enough spring to not "stick" on the upstroke. Using them in Browns will only increase the resistance a little and reduce the tactility. Something like "tacto-Blacks", but weaker. In all honesty I wouldn't bother modding Browns like this, since the difference will hardly be noticable.
In order to open the switches on a QFR you need desolder them, so it's a fair amount of work.
It's worthwhile first figuring out what you really want the switches to feel like before going to all this trouble.In my opinion, the "best" Cherry MX switches nowadays are not actually Cherry MX switches. Zeal has worked with Gateron to produce some switches with better fitting top cases and smoother sliders in both linear and tactile variants and they're both available at a discount price until end of this month. More expensive than stock MX switches, but from what reviewers are saying they're well worth it. They have tightly fitting fully transparent casings, smooth sliders and gold plated springs. Far from "ordinary":
https://geekhack.org/index.php?topic=74807.0I like to mod my switches with the little balls from IMSTO (
http://imsto.cn/index.php?route=product/product&path=61&product_id=88) to provide a softer bottom-out and I'll be doing this to my Zealios when they arrive, too. I also use a little liquid latex inside the top casings to reduce release noise. I reckon Zealios with those mods = perfection for me.
