I think the only 55g key is the esc key..
It goes from 30-35g on the pinky keys to around 40g on the ring finger keys to 45g ...Modifiers are 45g...don't know about numberpad because full sucks

. These are all just estimates based on using them...I think there is some sort of layout that shows this as well but the point is, it goes from easy to hard gradually.
It sucks for gaming IMO...but for typing its great...the biggest difference is on your pinky keys though..that's at least where I feel it when I switch to a non variable topre...For work or other things it just makes it easier on your hands.
I would also say you need to use "proper" form when typing if you plan on using it..if you hen peck or use your own form of typing, the variable keys will probably feel terrible and feel like something is wrong...but when you're using all of your fingers.
The only other part that takes a bit of getting used to is that if you rest your fingers on the keys, the light keys may activate...had a lot of aaaaaaaaaaaaaaaaaaa when I first got a variable.
I think most people on here dislike the variable but for work I think it is fantastic..
