Cant think of many outer blades with Limba top, maybe DHS Long 5A or Nittaku Acoustic Carbon.
Not sure about the properties of the fibers used in the Trinity, since it is made out of three materials. I only know of Xioms Trimetrix that has 3 fibers, but I think none of their blades are outer and have Limba.
The DHS Long 5A might be the best bet
