I have a fair bit of experience shooting landscape on most formats from 4x5 down to 35mm
When I was using a Hasselblad ArcBody, which also provided some limited movements I found i was never really needing any tilt
beyond 4-5 degrees to achieve sharp focus from a few feet to 'infinity' using the 45mm and 75mm lenses
Of course, there will be extreme situations where more will be required but i think you will be just fine with your camera choice.
FWIW, using the 24 and 45 tilt shifts on my canon bodies I'm generally finding that 2-3 degrees tilt achieve similar results for most situations where
I want extreme depth-sometimes more but not too often.
