Loop evotec spools?

[Tombass123]

Picked up a used G4 LW 7/9... it's a beauty.
Have it with a SA's mastery WF8. Only problem is trying to find spools that match up with it...
Do any of the older Loop evotec (G3 series etc.) fit the G4 7/9 LW? Or anybody know a good place to get Loop spools?
Need another for intermediate/ full sink lines for rockfish on the Chesapeake.
Does the 8/10 or 6-8 work for 7/9?

Either way I love the look and feel of Loop's design!
