I agree Efrain. Stuart Anslows books show many applications of the patterns(ITF)for SD. Though I'm familiar with Koryo,Kum Gong & Tae Beck from WTF, alot of the techniques are the same and therefore the same ideas would work for their apps. To say that TKD patterns (again mostly ITF), would also have to apply to Shoto-kan as that is where TKD is rooted from and many of the patterns are simialr.
