T7 is about as far as I went learning TKD forms. Perhaps the more modern ones that come later have better application built in, but the older forms are just karate looking dances.
My sons Yusool instructor told me he's seen recordings of the single weekend in which the (I think) taeguk forms were thrown together.
They should be dropped In favour of the Ashihara karate forms or something similar. Loose the pretence of a pre-20th century foundation and Base everything on modern fighting and self defence strategy.
