I had great results using Red Line MTL in my '90 Integra and '95 Civic. never got a try to use any SpecForm formula while I owned those cars.
For the record, the viscosities for the fluids in question are:
Spec. Form's MTL-P 12.5
Red Line Oil MTL 10.6
Spec. Form's Synchroglide 9.5
Given how far north you are, airbus, I'd opt for the Synchroglide.
