...I'm going to stay at 2.8mm & try it with -12mm & -9mm OEM springs.



I tested the 2.8mm slides with the -9mm (approx. 94mm OAL) chopped OEM springs. Much better stability with acceptable response. I'm still going to try a -12mm OEM spring in my quest to optimize the balance of response v. stability.

Different rate & length springs can effect the AFR at static openings, & not just a slide transitions.

With what I now know, the FZ1 springs are probably the way to go with pods & 2.5mm stock slides. That said, 2.8mm slides & OEM springs cut to the proper length may be even better...

I'm going to find out.
