BamaBows technically aren't Hill-style American Semi-Longbows. They are built differently. True they do brace to a D-shape like a Hill, but they are not deep cored or narrow-limbed like a Hill. They are built more in the flatbow style. Also the grip on the Bama is basically a reverse teardrop, with the belly side of the grip being wider, tapering more to a point on the backside. Quite the opposite of the wedge grip that Howard, Schulz, Swinehart and others (including me) prefer.
I'm sure that many people will argue that this is all just semantics. However there are specific differences in the design and construction of "flat" Semi-longbows and "Hill" Semi-longbows. Those differences may be subtle, but they all add up to a very different bow.
That said, I owned a BamaBow and it was very nice. Nate builds a beautiful bow. Great custom work and a heck of a nice to guy to deal with. Excellent bow for the price.
