Unsu and Gojushiho Sho have worked great for me. I won the 2003 WKA and WPKA World Champs with Unsu, and the 2004 WKA / IASKA World Champs with Gojushiho Sho. Both are great forms, but both require a whole heap of training to stand up in competition. Having said that, the best kata is the one that suits you best. Its all about bringing you own personal style to the kata, and in that eveyone is different. Good luck with the comps Paul Law
