Man, I gotta disagree with you here. That guy was being a jerk about it, but he also did you a solid, and you're giving him credit like he earned it. He didn't teach you anything, he just told you your board felt bad and then handed you a tester so you'd feel dumb. You already knew what heavy springs were, you just hadn't tried them side by side. The real reason your board feels better now is you went home and did the work, not because some rando at Micro Center tapped two keys. Next time somebody roasts your build, shrug and ask what they're running instead of letting it get in your head.

The "leave a part alone instead of chasing every little thing" line hits hard because that same thing shows up everywhere. People mess with stuff that works fine because they read one forum post or watched one video and now they think they have to fix it. Old cars, old houses, old cameras, it does not matter. A guy who has actually touched a hundred of these things knows what breaks and what does not, and half the time the real skill is knowing when to keep your hands off. Chasing every little thing usually just creates new problems that were not there before.
