Number or coils will make a difference also. All things being the same, the spring with more coils has less tension or rate of return (in this kind of spring) as each coil does less work to return the spring to static."harder". Not sure.
One is black, the other isn't,.
One is shorter than the other.
They are different springs.
Gauge wire used to make spring is likely the same. Length would affect tension as does screwing the adjustment.
Useless help, but hey. At least a made a small effort.
I've often wondered if there is a rubber band equivalent.
I found one. Premier EDP. I've never seen this pedal:I think there was a Premier pedal back in the 90's that used a rubber band thingy. It was their pedal that looked like it came out of a TRON movie. No clue what the name of it was.
Oh, haha, I'm just interested in the sliding weight. That seems like it would fine tune the sweet spot.Here's 2 of them (not a double pedal).
