Or just keep it all 'folded' as I did, and 'unfold' just a few (Business and Soldier, and, in rare "career path" occasions, take some others out of the cascade), then you'll have a little more than 34 skills. Also the heavy use of cascades will increase player's choice while still keeping the careers different.
And Archaic Weapons exist as a seperate cascade group for the sake of Barbarians - they get heavy use of it and of Melee Combat instead of Gun Combat. Most people from TL5+ won't know how to use a bow, and if they do, it'll be part of the two "pre-service" hobby skills I intend to give each character.
And Fritz88, thanks for the advice about melee combat - I've edited the list accordingly.
