I joined the forum for the sole purpose of making two remarks: 1) As a long-time Tae Kwon Do artist who learned a sportier style but has retained what my dad and I call the "mean" parts of the forms (or patterns, or poomsae, or kata, whatever you like), I appreciate deeply the efficiency and simplicity of Diagonal Lines, and Watch Your Back, both of which I'm working on absorbing into my muscle memory and databank of techniques, should I ever need to employ my pistol "for real." 2) Bassai Dai (called in my school of TKD simply "Bassai") is my favorite form, because it's aggressive.
