So I've been reading (and watching the videos) of all these low-recoiling 14.5" middies with heavy buffers and springs and I just wanted to make sure I was thinking this through correctly...

If I were to upgrade my buffer and add a heavier spring + a comp of some sort I'd get similar results with my 16" middy, right?

So looking at the options from Sprinco, there's a blue and a red. The blue spring is not any stronger than a standard spring, but is CS and should last longer, while the red is extra powered, is this correct? Basically, upgrading to the blue spring will have little to no bearing on the recoil of the rifle, in comparison to where it is now, right?
