It's been some years, but I remember one or two things about the 60:
A lot of issues with getting the APU going. Something to do with a fuel-atomiser, I was told?
Getting to the batteries if an APU is installed is tricky, in fact a lot of maintenance-access is tedious, which can slow you down during an AOG-troubleshooting.
Starter-gennies let go every so often.
Poor runway-numbers, as everybody has mentioned. Also you want to bear in mind that, whilst Russian runways are long, the surface is often very poor which makes for a jarring ride on those tiny wheels.
Moscow-Dubai is possible, we did it.
Wing is happiest at around 400, maybe slightly above.
Enjoy the rocket.
