I picked up the ICM 1/700 Grosser Kurfurst because I saw it billed as any "early war" version of the Konig class. FYI - it has torpedo net BOOMS on a G sprue, but there is NO rolled up torpedo net that I can see anywhere in the kit or instructions. I built the Flyhawk 1/700 Derfflinger a couple years back, and the torpedo net was essentially a long flexible plastic cylinder (so I'm planning to use some of my plastic bar stock to stand in for the missing torpedo nets of GK). There was a hint of detail in the rolled netting on Derfflinger but not much.
(I suppose one could buy a Derfflinger kit for the torpedo nets... Pretty sure it's a longer ship than Konig. It also has PE included, even in the basic kit ($30 version). Very nice inclined ladders (perhaps useful) and a lot of precut railings (perhaps not as useful).) All comes down to how much you want to spend.
