No it's not the luggage because it behaves more with panniers and topbox or either on their own.
I have a MRA screen thats quite large. I suppose that could be contributing factor but I think the main issue is the rear ride height. Tyres are PR3s in good condition so can't think they're a problem. The head bearing + all wheel bearings are okay. Besides the only thing that changed before I got the weaving was the shock.
That's right and is the main effect of shorter dogbones and resulting steeper fork angle. I know the standard length is 140mm whilst I'm pretty sure the + 25mm bones are 135mm. If you've got 130mm bones, I'm guessing that'll equate to around +50mm? That's quite a bit of difference and is likely to be the cause of any twitchiness. Sounds like we're in the same boat. I think I'll have to get the shock changed back to normal length.
So the moral of the story is to bear in mind your weight when choosing how much you jack up by. Bugger.
