Left handed sequence help needed

[ens_audio]

Hello, they're a few riffs that I've been working on from various tunes but they're a few riffs that I am having trouble with as far as trying to apply the most "ergonomic" sequence as far as the left hand goes...here a few examples if somebody can give me their input on what L hand fingering combination they would use.

Obscura - Universe Momentum

They're a few other riffs that I'll eventually post once I get some help with this

Thank you,

Two words: position shifts. If you use those fingerings, that's your only choice.
