I've been trooping with my Hyperfirm E11 for a while now, and have been very happy with it.  Without getting into the details, it's definitely sad that Hyperfirm blasters are no longer made, since HFx Productions is no more.   Somewhat on a whim, I decided to snap up a blaster from Praetorian Blasters, to see how they compare to my Hyperfirm.  I got it a few days ago (a little under 3 weeks from ordering, IIRC), and snapped a few photos to compare to my Hyperfirm.  Sorry all the angles
