Hello Positron,
The Copper Canyon is a big place, it really depends on what kind of ride you want, Road, MTB, Tour?
From Basaseachic to Creel is a very nice road that could be done in a couple of days or a really long one, maybe your best bet will be if MTBing to ride around Basaseachi for a couple of days and the move by car to the Creel area and spend 3 or 4 days there. Its beautiful country.
Check my blog, I have several Garmin maps so you can get an idea.
