Which spring weight should I get off Massdrop?

Nevermind. I'm an idiot. It comes w/ all 3.

Check the discussion page.  I wrote a summary.

35g - Lighter than the spring used in MX Red/Blue/Brown. Clear stems and possibly even brown stems will stick on the upstroke. Lube recommended. These can be good for blues/greens/whites.
40g - Slightly lighter than the spring found in stock MX Red/Brown/Blue. Clear stems will have a slight stick on the upstroke until they are worn in.
45g - Same weight as stock MX Red/Brown/Blue spring. Clear stems will be slightly sticky on the upstroke until broken in.
60g - Same weight as stock MX Black/Green/White
62g - NOT the 62g that modders use in "62g Ergo Clears.". Heavier than stock black/green/white.
67g - Significantly heavier than stock MX black/green/white. Heavier than stock MX clear springs, and with different force curve.
80g - Heavy.

Remember that Korean springs are actually lighter than cherry springs.

Korean springs are measured fully compressed, while Cherry springs are measured at actuation (half way).

Personally, I like 62g, 55g, and 67g springs. I have 62g in my QFR (MX blacks), and they're pretty sweet.

Aren't these Gateron Springs? That would make them Chinese. I'm not sure they follow the same convention were used to.

Read the discussion page.  Alex from MD did a nice nickel test and provided correct actuation forces (using linear stems)

Alright, I've constructed a nickel tester out of the key tester and some leds. I used 7 red switches with their springs replaced. The keycap being used weighs 3.2 g so it's a little off, but it's the flattest key I have without sanding one down. The weight listed will be where the LED turned on.

For the sake of simplicity, I'm just rounding up the keycap to count as another nickel. You can see in the first switch that it activates with either 7 nickels or 6 nickels with the switch so it's probably somewhere in between the two, but if someone wants it more accurate I'll figure that out later.

I hope this will help rather than make more confusion, but let me know if you have any questions.

35 g spring - 35 g
40 g spring - 40 g
45 g spring - 45 g
60 g spring - 60 g
62 g spring - 65 g
67 g spring - 75 g
80 g spring - 80-85g

I don't understand this line:

>60g - Same weight as stock MX Black/Green/White

Someone please correct me if I'm wrong, but don't Black, Green, and White all have different weights?

Green and White have the same springs. Black is slightly lighter. [source: ripster's imgur album]

Disagree. Black is substantially lighter than Green. See this TechReport article:

http://techreport.com/review/24461/a-first-look-at-cherry-mx-green-key-switches

Black is 60cN and Green is 80cN to actuate. Huge difference.

The whites I have used aren't as heavy as greens.

My green and white feel exactly the same.

Maybe the click loudness threw me off. But the greens were more fatiguing.

When I remembered which one was the green and which one was the white I could have sworn there was a differnce, but I don't know which one is what, so they feel exactly the same to me.

From my post on MD and on the GreatFinds thread:

I took this photo last night

Also put green spring with a linear stem and compared it to a stock black by pressing them into each other.  Black and Green are pretty close.  But grey is much heavier.

Not the most scientific experiment but its what I got.  Could be doing something wrong.

Rispter says they're different and in his album, the black spring is different from any black spring I have.

Rknize on GH says they're the same.

My tests show they are similar, and greys are in another league.
