I saw both of them in Tarifa (did I mention I was over there ?

) , exactly what CJW said, the plus+ has the front wing extremely at the front and is really powerful, they both come with a set of different width shims.
The Alabau sisters (that I met in Tarifa, spain

) told me the plus+ was a too much of a handful for light to medium weight riders, better suited for big blokes. (they even wanted to sell me theirs, too bad it wouldn't fit in my luggage)
