All that wasted time wrestling with leaf ping by carefully keeping the leaf and stem legs bone dry. I probably should have noticed that good factory lube jobs put a healthy coat of oil right on the leaf and legs but I didn’t. If you have 105 for springs, put a swipe on the tactile leaf. The tactility remains despite all that wisdom about carefully avoiding the heckin’ leaf and legs!!!1 The leaf ping does not remain. My tactiles don’t magically become linear and my heavy tactiles don’t magically feel like browns. Do the rails with 3203 as normal. If you only have 3203, a very light bit on the leaf is still fine Or just do the whole switch with 105 and lube the whole thing. I feel like a child who has been told that swallowing seeds will make trees grow in your belly, I just believed it. I thought I had to just cope with leaf ping to preserve tactility. It’s not true don’t fall for it. Use a light hand and you can have the best of both worlds
Lube the leaf on your tactiles with 105. If you use 205 on tactiles like a caveman you’re still beyond saving. That’s my rant, ymmv
With my first and only custom build, I got Boba U4T switches and initially followed the advice that they shouldn’t get lubed. I used it that way for a few months and enjoyed it, but thought there is some scratchy feeling that I can get rid of. I basically ignored all advice and put a light lube on everything, and I’ve been incredibly happy with the results ever since. I really don’t understand where the myth of lube ruining tactile switches came from.
generally it’s gazzew recommended to not lube it but i think literally nobody follows it. every single u4t build has them lubed. i have them lubed. i don’t think it matters much. you don’t even have to gazzew method it, just make sure you hold down the stem when closing the switch so you don’t risk the tactility.
