Hi Seak,
A way to do it is by using the vector twice ,for instance, \vec{\vec{T}}. Not the more stylish way, but simple and effective.
I see you proposed other ways, but for me this was simpler, hope it helps.
Best regards,
David.

You also have the `esvect` package and its \vv command. Furthermore, you can choose between 8 different arrow tips.
Best regards to all,
