Variable vs Standard 1911 Recoil Springs

Working on selecting the right spring for my 1911 (45 ACP) and for me 13 lbs was the ticket using a variable recoil spring from the tuning set from Wolff that another shooter gave me. This spring was a variable, which I haven't used before and wasn't familiar with.

Is there a benefit using variable (progressive) recoil springs over the standard recoil springs for the relatively light loads in BE (4.0 gr of Clays) or is it simply use what works and experiment to find the optimal spring for your particular load/pistol.

Cheers,

the variable's are a little more forgiving than a standard spring so if it function's good use it.

I found Wolff's variable recoil springs a bit more forgiving when developing light loads for the wadgun.
Forgiving means they were a bit more reliable in feeding and ejecting over a range of light loads than conventional springs.

I use both variable and conventional springs - I use a spring weight that ejects the case so it lands about 6 feet away as per Wolff's recomendation.
