i've never understood what does the line "To get behind this sun and cast my weight" means... any ideas?

I think it might mean that he is casting the "weight" of his problems on his shoulders into the shadows, behind the sun. Meaning that all he needs is to be free of his burdens.

@jupiterisland Haha I signed up to SongMeanings just to answer your question! Personally it's clear to me it alludes to the SLINGSHOT manoeuvre -the song is about freeing oneself from a burden/ berievement/ 'basel' lifestyle by mentally allowing lifting /floating to a much higher plane -thereby 'casting the weight' of the previous limiting lifestyle.
