As mentioned, get a sturdy mono pod. You might use a spindly tripod with success,
but with a mono-pod, you only have the one leg. Ensure it's a strong stick.
On tripods, I prefer a pan-tilt head. On mono pods, only a simple ball head is needed.

Also, for landscapes, have you ever considered a 'bag pod?'
I shoot TLR, and MF SLR, mirror lock up with my bag pod.
