10540 that did surprise me you say that, I know you fly long trips and so does virtually every Cirrus owner I know in the UK and the rest of Europe.
Regarding Glass or Steam guages I think for me it took it a good 50 hours to get reasonably comfortable with the glass and while I know there is still a lot to learn with the GNS 430's and other kit I feel very comfortable after about 200 hours and would not feel confident with going back to traditional gauges without some serious re training and practice, I guess it is just whatever you get used to.
