It's a good idea not to take off or land as part of an Auto mission, so that part is good. But when you say take off "manually" that implies taking off without GPS.
Taking off manually (without GPS), and then switching to GPS once in the air, is something I've always done for safety. In the old days (i.e. 4 months ago), a GPS glitch could send your quad slinging sideways just a few feet off the ground, inevitably in the worst possible direction (toward nearest human, tree or boulder). But with the Solo, after the first firmware update, I've been growing more and more confident in taking off in GPS mode. For the last couple weeks I've been doing it every time. This is a new habit for me, but a lot easier - especially in windy conditions.
So my personal opinion is to change steps 3 and 6 to take off and land in "GPS Assisted" mode instead of "manually."
