I am fully convinced he's switching to TF now. He went to "pick up the new weapons" in Antwerp, close to where Dieter Calle is based (insta story two days ago). Today in the Youtube live he says he has been doing customizing work these days and learning a bunch of things, and then basically gives the whole TF marketing speech of the 2025 T-Fights (how swingweight has been dropping on the tour, due to balls coming up faster, etc).
He reacted to someone playing with a 345 SW in the comments and said his stick is around 290 unstrung 310 strung
Someone else asked what model he is switching to: "not an Aero 98, not a Percept... waiting for papers to be signed to tell more"
Finally, Karue states his favorite patterns are 18x19 and 16x20, so I would be surprised if he switched to something other than a 305S or an "underspec" ISO 305
