The other two should be without any trouble.
Many buyers are simply going to equate price with quality and I imagine there is some truth to that here, but if doing mediocre length OCI's the Magnatec is the way to go IMO.
I guess we could say the Magnatec is a 7.5K oil, the black Edge is a 10K oil and the gold Edge is the 15K oil...but many will run the Magnatec for the full OLM and probably do very well.
