Primary spring Vs Secondary spring

Fight each other? I don't know.

I'm gonna guess number one will load an M7 hard off the line, if you run enough weight to keep it in the powerband with that primary spring, and backshift slowly, top out at 85mph, depending on helix.

I'm gonna guess number two will backshift even slower without alot of preload.

I ran the DnD maroon for a bit (110-340)...and it helped backshift, but I felt I needed more secondary spring initially, and less at final shift... It needed nearly as much preload to backshift as the stock white, and they have the same inital force.
