Mexico: Saltillo to Parras

[Mike in Clear Lake]

I am looking or any information whatsoever on these routes from Saltillo to Parras, and the towns in between. These are routes south of MEX40(C) and would be run on a street bike. Listing the towns from east to west:

Option 1
SALTILLO
La Noria
Porvenir de Tacubaya
General Cepeda
(the above are tertiary roads that merge with secondary roads at General Cepeda)
Guadalupe
Guariche
PARRAS

Option 2
SALTILLO
(the below is an all secondary route)
Refugio de las Cajas
San Juan de la Vaqueria
El Derramadero
El Rancho Nuevo
General Cepeda
Guadalupe
Guariche
PARRAS

Thanks in advance,

Mike
