I currently use the kinvara 3, the NB MT10, the trail glove, the BA2, the vapor glove and the cursoris. Although the cursoris just got me injured a few days ago so I can't really say I'm using any of them anymore.
My limited experience with the Cursoris leads me to advise against it. Durability seems bad as far as I can tell (wear is significant after barely 50 miles) and the shoe in itself is unsafe at higher paces unless you have very stable ankles.
The BA2's soles are way more flexible than the Cursoris'. I do not recommend the Cursoris. It's way too soft and gives a misleading sense of security. It also becomes quite sloppy when picking up the pace.
It seems to me the closest thing to a Vapor Glove with cushioning would either be the BA2 or the Ascend Glove (although I haven't tried this one.) I can't imagine the flexibility of The One being anywhere near that of the Vapor Glove.
