Would the king post need to be 10" wide with a narrow bent like this? And how far up the rafters is safe for the brace-king post connection?

Also, since the king post and tie beam could both be considered to be under tension, how does that affect the choice to use a continuous tie versus a continuous king? I'd rather have an 18' tie, using a king post with wedged half dovetail and a 1st floor post, than a 20' or so king. Thanks!
