I'm stuck between North West Fabs and ORDs doubler kits. I've seen ORDs take some abuse but I like the clockability of the NWF doubler. Cables shifters seem like there Easyer to deal with rather than the linkage setup. Anyone know strength and and length differences between the two? Any input is appreciated. Subject has been beaten to death and I've read a some forum posts already but it seems like it's more opinion than anything.
