Class 3 shields? Did you mean scb? Distant worlds is a travel thing, not combat. Busting out scb while firing back and maneuvering will require heat sinks and the python doesn't have an extraordinary number of modules to choose from so it's the sort of sacrifice that's felt. The Python is great fun but these days it just is not the most effective shield tanker.Have to disagree with the heat management, im on the Distant Worlds expedition with my Python and no problems whatsoever with heat when for example fuel scooping, even from F class stars even with class 3 shields.
