Too much swearing and way too sarcastic for my taste. Got a few minutes in to the video and turned it off. The snide remarks and excessive sarcasm and the general you traders don't know what you're doing attitude was too much.
The ironic thing is, there IS a lot of useful advice in that video but most of it isn't what the video focuses on.
If you're the sort of person who doesn't already know this stuff and you're buying a T7, it's probably because you're fairly new and you've just scraped together enough credits for your first big ship.
Which means you're probably
not going to have Cr50m lying around to upgrade it.
That being the case, you're probably going to prefer to just fly it in Solo rather than risking it in Open.
Conversely, if you're the sort of person who's cool with risking a T7 in Open, and has the credits to upgrade it, you're probably going to have a fair idea what you're doing.
Having said that, the actual in-flight advice he offers about how to defend yourself and how to escape is pretty good information. [up]
In general, though, it's a bit like:-
"How do I fit a sofa into the back of a VW Golf?"
"Well, you start by replacing the VW Golf with a Toyota land Cruiser....."
