Erion 2-1 system

I apologize for the both these charts being black & white, hopefully I will have color charts soon
I manually highlighted the dip of the 2-1 on a copy of the comparison chart
of the 2-1 against the mori high mounts

These are two different charts from two seperate owners of the Erion 2-1 system

as you can see it kills the mid-range
