Meditation/contemplation: Finding A Balance

[AMS]

I have a formal sitting meditation practice set up and also a formal sitting contemplation practice.

Since minimising my lifestyle somewhat I also find myself with some spare time when I am just sitting (informally) doing very little.  I am never sure if I should be using any spare time I have throughout the day (such as being on a train) being mindful and getting in touch with my senses (meditating) or rather contemplating certain topics...  They seem to go directly against each other because one involves less thought and the other more.  Or is it about being especially present while contemplating and treating thought as another sensory phenomena at the same time as focusing on it's content?

Also do you guys have a list of insights/concepts that you contemplate which you cycle through per session or do you just go with whatever you resonate with most in that moment?

Thanks in advance!
