205 vs 205:105, better for Tactile and Linear, common mix ratio 205:105

[QuocTrong]

I usually use 205G0 for linear and 105 for tactile , recently i think about mix 205:105 lube tactile , is good ? i dont't know popular ratio mix 205:105 . What are the strengths and weaknesses of lube 205:105 oil?  help me

Thicker lube (205), will feel more smooth, but can feel sluggish at first, especially on lighter springs.
Thinner will feel snappier but not as smooth.

Thinner (oil not grease) lubes are really difficult to use too much (apply sparingly), and need little to no settling in period. While snappy, they will not match the buttery smoothness of thicker lube.

With stock light springs and a grease based lube such as 205 the slightly sluggish feel will fade as the grease settles in, provided you didn't use too much. If you use too much, it will need to be cleaned out and again be allowed to settle in. I've used similar lubes on moderate tactile switches into the 40g bottom out range, it's a bit tricky, but doable. You need to be careful on how much and where you put it, but you can get away with it. Took a couple days to settle, first time I did it I had redo a couple, second time I think I had to redo one. Going with even softer springs and higher tactility is is going to be extremely problematic and some switches may never even work properly, however few switches are THAT tactile and few people run them with such light springs anyhow.

If you use heavier springs (75g bottom out or more), there's little reason not to use 205 as opposed to thinner 105 as it will settle in fast, especially on linear and it shouldn't feel sluggish.
