I'm not totally certain what your question is but generally if you want to take landscape pictures on MF you're going to need a tripod all of the time with an SLR. If you go with a rangefinder such as Mamiya 7/Bronica RF645/Fuji 690 etc then you can use these more like travel cameras and shoot handheld successfully if required, although even these really require tripods if you care about quality.
Things like the Pentax 67 have horrendous mirror slap. You not only need a tripod but you need to use mirror lock up too if you want anything sharp.
I'm not saying that you can't use MF without a tripod (there's a huge body of work out there that proves this), but realistically this is the only way you'll get decent quality.
