The American Semi-Longbow that is under 6 ft. and different from the English Longbow over 6 ft in limb design and length. The reflex-deflex longbow and hybrids are shorter under 5'6" and generally faster than the first two. Although, there were exceptions recorded in Dan's two books, below.
Dan Bertalan wrote in "Traditional Bowyers of America" in 1989 and in his updated "Traditional Bowyers Encyclopedia" in 2007 about the bows of different bowyers of the time. I recall that Dick Robinson's Mystical (R&D) was as fast his two recurves the Peregrine, and Falcon T/D.

The other objections IMO is the added weight of a recurve with bow quiver (5 lbs +/- vs 1.2
