That's how I have it now, been trying various combinations. With the Galloway sear spring and all other Apex springs, it's still @ 5.75 lbs. If I leave it alone at this point, maybe I'll call it a "Gallapex"! This is the lowest lb. rating I could get. I'm hoping some Galloway users will chime in to see if they're getting the advertised "3.5 to 4.5". Galloway seems like a good company, maybe I got a bad run.
