Thanks @djmantis, good advice.
I have experience with the switches in question.
The SP Star Meteor Orange is basically an MX Brown. However, I find the tactile characteristics to be relatively good.
The Meteor Orange has good pre-travel, maybe 2mm like Gateron Brown. I find that the tactility subtly ramps up and there is a definite but minimal tactile event. You know when you’ve hit it, which makes it better than some Gaterons I’ve tried.
The annoying part of the Meteor Orange is that it is noisy. It slams almost like it has a long stem, but it doesn’t. The slam seems to be caused by the housing. It slams less if you try other housing materials.
Here are some things people have done to tame the sound on SP Star Meteor Orange:
- Lube over factory lube with either 105g0 or 105g0/205g0 mix.
Apparently, you can lube everything [housing, stem, spring] with 105g0, and it should be okay.
Film switch - KBDFans films will work, but apparently the best results may come from 0.15mm TX.
Springs may be a source of noise, so it is possible that 57 G 15mm TX springs should be used.
One person replaced the tops with Cherry tops, which is probably sorely needed.
So that is what I’m going to have to investigate. I also recently ordered a package of SP Star Meteor during the AliExpress sale. They are normally about 70 cents each [CDN], but these were 56 cents each.
The other switch type in question here is the Durock Light Tactile. As DJMantis pointed out, Pewter and Durock Light Tactile should be the same design.
I ordered 70 Pewters to Canada [the most expensive MX Browns ever] and tested two of them. In fact, they were side-by-side on a keyboard with SP Star Meteor Orange.
I did not like the tactile characteristics of Pewter as much as SP Star Meteor Orange. I found that the pre-travel was less definite. It was more of a resistance at the top, and once you clear that you get the rest of the bump and then it’s over. It’s not as gradual as MX Brown or SP Star Meteor Orange. It was like presssssssssssss > slam to me.
However, the comparison is unfair because IMHO the Pewter switches were lubed inconsistently from factory. So if you use them, they might be kind of waxy or gummed up or something. Just not lubed the way a pro would do it.
I took the Pewter stems out and put them in Taro Ball housings, which is a Durock Medium Tactile. There, with 57 G springs, they seemed to perform more to spec. Like light Browns with a noticeable bump.
The Pewter beat Meteor Orange hands down in terms of housing tightness. If you have Pewters that are lubed the way you like, they won’t need as much work for optimization as today’s other light tactiles. Very little wobble.
Despite the good housing fit, the sound was mediocre. It wanted to thock, and the factory lube helped, but it was still kind of higher-pitched than a Cherry housing.
I am not sure how I feel about Durock’s new tactiles.
My problem is with the stem design. For Durock Medium Tactile [what a cumbersome name], they seemed to shrink down the T1 stem and use a less aggressive leaf. The T1 uses Panda/Zealio-style tactility, so it’s all top loaded then it collapses.
You have to be careful when doing this with light springs, and low resistance, because it can become very ‘slammy.’
Pewter stem felt to me like a further scaled-down Medium Tactile stem. Still didn’t have the subtle, pre-travel friendly curve of Cherry and Meteor Orange switches.
So, all-in-all, the Durock tactiles usually have excellent housing fit. They often sound excellent on polycarb plates like on the KBD67 Lite. I question the stem shape. The Pewter leaf felt a little ‘dead’ to me, and not because it’s a light tactile. I’m not sure Durock has its leafs sorted out, although they’re getting there.
If you are looking at these two switches, I also recommend TTC Watermelon Milkshake. It seems to be somewhere in-between a Brown and Ergo-Clear. I find it is too punchy and operating at a higher-than-necessary weight stock, so something like a medium 57 G spring might be better, or even a 65 G Progressive.
Both Meteor Orange and Watermelon Milkshake are likely to need lubing and filming, at least the Durock switches mostly don’t need filming.
