best program for rte export

For many years i have been using fsbuild etc but I find it is not up to date and really does not deal with some of the latest aircraft requirements for the creation and export to various fmsI wonder what others would recommend for fsx as a good route creation and export toolI am using allot of wilco feel there aircraft, pmdg ( incl md-11) , isg modified ,cool sky and of course fsx native aircraftIn the past I have used fsbuild, vroute, simroute and fscommander,What is the best route creation tool out there and am I missing something that combines all of the aboveThanks Peter
