Opinions on these "custom-50m-metering-rods"

Compared to the standard original 50m(etc) primary rod with .036 tip. with the dual taper/step

Im wondering, all things being equal, if these "custom" straight taper primary rods would need a larger jet to  run the same as the original dual taper with same size jet. Especially at off idle tip in.

Im wondering if I remove my Custom 50m rods and install my original dual taper 50m it would be richer off idle acceleration , all things being equal

I thought all OEM "M" rods had a smooth taper to the tip and no "step" like K rods, etc?

No step, but the original rods had a "dual" taper near the tip.
