Gorilla glue is my preferred choice - sticks very well. The super tough is very good, but it expands a lot (you have to wet the surfaces to be glued - then it really expands). The resulting foamy lump is difficult to remove if it goes on the surface finish - and its no good trying to wipe it back as it keeps expanding for quite a while. It would be excellent on joints where it wasn't going to spoil a finish as it really does stick well.
I would also look at how I have placed the wedges on the corners - although if it was glued I doubt that a well placed wedge would make a huge difference. Tulip cuts with a very clean finish on the Morso - this can sometimes make getting good adhesion difficult and a little scoring on the face of both surfaces with a scalpel might help.

Re: Nightmare on Tulipwood Street
If I cut a shiny face on a piece of oak I sometimes drill small holes in it to allow the glue to penetrate. Particularly on small mouldings. The theory is that it allows excess glue to form a sort of bridge.
Don't know if it does any good, but it makes me feel better.
