The old electrical nerd in me wants a Class A, too. Mjolnir 3 's numbers arent that impressive but it does seem like with Class A power less is needed. Im definitely on a knowledge hunt this week as I figure this out.
One thing that did give me pause was Ive seen a few people mention that Aune s17 isnt the best synergy with Hek, not entirely sure if they mean across the line-up of just on HeKse, but, yeah. Doesnt make much sense to me that an Aune s17 wouldnt be magical with HeK.
I bet the Aries is pretty great on HeK.
