Whoa scratching Helm would be a mistake. Before this season I would agree with you, but as of right now he's actually playing pretty well. I would like to see the youth movement as much as many fans, but I think Helm should stay up. If scratch Abby he's awful.

As of right now, Helm DLR and abby have not been on for a lot of goals against. Once abby is healthy I would like to see them back on a line. Helm is producing just fine as a fourth liner and with not being scored on they have looked good together. How you have the first and second line would be nice to see how it works out. Even give Perlini a chance beside Larkin for a couple games to grow some confidence.
AA and Mantha should have chemistry as they are good friends and playing with Hirose will help both get more changes. Hirose need to get back playing with confidence, right now it seems like he is forcing to many plays. Bert and Larkin create a good offense already where perlini may help.

Bert-Larkin-Perlini
Hirose-AA-Mantha
Fil-Neilsen-Erne (when glenny is back he can sub in between Erne or Perlini depending on production
Smith-DLR-Helm (when healthy go with Abby instead of smith)
