Mike,
For my money, the Hasegawa kit would be the best for the job. The particular aircraft you refer to, which appeared at the 2006 NATO Tiger Meet, is actually a bit of a mystery to me. In spite of being designated a F.1M (M for Modification under the Spanish system), this aircraft would appear to be one of the attrition replacements purchased some years ago from Dassault by Spain. It totally lacks ANY of the leading or trailing edge fin-mounted fairings for IFF, RWR etc. The only aircraft that had this feature were the first 20 or so produced for the Armee de l'Air in the early 1970s. All
