I would continue to go 11-7 with this team to be honest. Gives marty a chance to get Jelsma or Hemming an extra shift every once in a while and not like anyone really deserves the spot. Plus I think Armstrong has a chance to gain some confidence and be a good player. He has the talent he just needs to get more comfortable.
I think especially with Bertucci out he definitely has to move to one PP unit instead of trying to spread it out. I would go 28 and 77 on their one timer sides with 86 up top 53 in the middle and 29 in front. Especially if 81 is suspended.
