Ben,
I'm the original owner of Hasadari's Mark King. It's a King standard - medium scale, mahogany body, cocobolo top, signature electronics. It's a very nice bass. It's heavy, with the standard point body & cocobolo top, but balances well & was very easy to play with the 32 inch scale. I've never played a Series bass before, so I couldn't compare & contrast it. The only thing I would have preferred on it & my current SC deluxe is to have the neck pick up located flush up against the truss rod cover. All in all, it's a great bass & I wish I still had it. Also, Bob is a good guy to deal with. Good luck to you!
