Personally, I would probably split Raymond and Holtz to two different lines.
Partly because I want to have 2 lines that consistently can push the play to the o-zone, and partly because most of their scoring chances are easily stopped because both of them play too much on the outside.
When it comes to Raymond, I would like to try a “Frölunda” line consisting of Fagemo – Henriksson – Raymond. During the previous season in SHL we saw that the Fagemo – Hjalmarsson – Lasch line worked really well, and I think this line would work in a similar manner. Raymond (IMO) plays a quite similar game to Lasch (although Raymond is probably more complete with being better defensively and a better shot). And Henriksson has shown that he has the hockey-IQ to play with stars and is good defensively. Fagemo will do as he always does and go straight for the net, which will either make him a passing option for Raymond, or open up space for Henriksson to get a shot off.
When it comes to Holtz I would like him to play with Gustafsson. I could see Holtz - Gustafsson – Grewe working, being somewhat of a junior (and less skilled) version of Capitals Ovie – Bäckström – Wilson line. Another option would be Holtz – Gustafsson – Hållander.
Gustafsson and Henriksson could of course swap places, but I think the familiarity Raymond has with Henriksson might be preferable.
