I haven't seen much of Leddy's shot but I do know that Boychuk has a mega cannon so not too pissed about him being #1 PP. I do agree that Boychuk should be the #1 option on the PK. With our train wreck of a PK, we need all the defensively sound players and the fact he can move bodies should be used so in order to not have him playing 28 min a game, Leddy should be the first option on the PP.
That's my thinking. It's not too complex, its basically common sense.
The more I think about it, the more I would like a de Haan - Boychuk pairing. Just staple those two guys together, have them be the shutdown tandem on even strength and first pairing PK. Both are nice options on PP in a reserv role but wouldn't want to burn either out, they are both too important at ES and PK.
I think Leddy is ready to emerge as a #1 PP option. Plus, I wouldn't want him getting much burn on the PK, so you can load him up all you want on the PP. (Same could be said for Viz.
Hickey-Hamonic would be an excellent 2nd pairing PK duo.
Personnel wise the PK should be MUCH improved with the additions of Boychuk, Halak and Johnson. But with the coaching, I'm not convinced it's going to work out as well as it should.
