Which brand is the better brand to get I know Promy springs are pretty good, as well as PDI, Which one will give me a nice FPS (400-420 w/ .25) while not splitting my gearbox? I have a KWA M4 BTW. And what does non-linear mean I know it's better but why?

The stock spring will give you 400-420 by default. Just add a TB barrel and you will be 425 or better.

.25 are better for a 400fps gun anyways and better accuracy.

A non linear spring effectively is easier for motor/gear to compress early on in the cycle. It gets harder towards the end when the momentum/inertia gives a helping hand to complete the compression cycle.

A type zero cylinder and TB barrel should give you about 400fps/.25 with a 130 KWA spring. The KWA spring is about an inch shorter then the Guarder I used which gave me about 430fps/.25 when I ran that setup.

I just went out an got a madbull M100 spring a couple days ago, apparently they are the "best" because their scientifically tested, I don't really care. But I do like the colour of the spring (blue) :lol:

From what I hear the spring color will eventually wear off and leave a mess in your gearbox. That's just what I heard. BTW I have decide to go with PDI,  I have asked several prominent airsmiths what is there recommendation and they have said that they would go with a PDI, but I'll probably save that set-up for my M16, mainly because I wanna keep my M4 field legal. I need something to use at sponsored ops. Thanks for all the help, and explanations, and does anyone know where I can get a KWA M130 spring from. They don't seem to be selling them yet in the pro-shop

We don't have stock m130 spring at the moment.  I would just pick something else off the shell from other retailers.
