Looking at the slip that came with my recent Happ comps it shows a "heavy" spring option.
I went to Happ's website but they don't list the specs on the springs.
does anyone know the strength of the standard and heavy springs?
95-1309-00 / 95-1309-01
Im more curious than anything I honestly wouldn't want a heavier spring then the standard,
Infact I wouldn't mind slightly lighter but it's hard to know what that would be without first knowing what you start with.
It looks like the Ultimate uses the same springs if im not mistaken.
