FWIW, the gun feels much stiffer with the new coil spring (factory weight), but I'm guessing that's because my old flat spring had lost power after a few years, and now I'm back to OEM spec?
Would you like a straightforward answer?
Wolff Gunsprings are the finest product of their kind in the world! High tensile strength, round wire coil springs hold their strength for much longer and are more flexible and resilient than flat wound springs.
I, once, asked Dave Koebensky at Wolff, 'Why' they didn't make flat wound springs. Dave's reply? He said,
'We're a big multi-million dollar company.' 'We can make any kind of spring we want to; but, all of our tests on various brands and types of springs have convinced us that flat wound springs are an inferior product to what we're producing now.' 'So, don't expect Wolff to be selling those things anytime soon.'
PS: You said that you were using a, 'factory standard' spring. Danny's right! That would be an 18# spring. I suspect you've been using an under-powered spring for a long time. So, I got 'a ask, 'How's it shoot?'
You do know that Wolff's custom springs go on their steel rods from only one direction - Right! (Small end first)
