After swapping in a set of .48 springs in my 45 shivers, I have found that I have perhaps went to a heavier than needed spring. I got to thinking, what if I ran one leg with the .48 spring, and the other leg with the stocker? I have heard of folks running mismatched springs in other applications, but I wonder is there a round about range where the difference between the two spring rates would be become unacceptable? Anyone have any experience doing this, and if so what sort of difference in rates were you working with?
