I suppose I do things rather like yourself. I use Jep Flitestar to plot route and use RNAV (When in a KNS80 equipped Aircraft..i.e NOT the seneca!) to feed the HSI..which feeds the Autopilot roll mode (in the archer). But I am going to try and not neglect visual navigation as much as I used to because when all else fails (...the other day) its the only thing you have!
