Your pairings make my head spin.
Hughes and Edler are LD. Myers and Rafferty are RD. Tryamkin I think is more comfortable on the right side but I agree he can play on the left. From memory, I think he is better on the right side.
I'm not a fan of playing Dman away from their natural side (and I'm not talking about whether they are a left or right shot) even if they aren't disastrous playing the other side. Kind of like when we had Garrison and we played him on the left side. He wasn't bad but it just doesn't work well.
