I'm going to leave this up to the players, as I could go either way. There are two options:
Option 1:
Standard AD & KH skill system. In this case, everyone would start with something like 300+ XP to build out their skill set so that they have a strong KH skill with it's prerequisites and a good rounding of AD skills.
Option 2:
Use the skill system from A Skilled Frontier with some minor tweaks to the exact skills and skill areas. In this case, since you can start with spaceship skills from the start, the total number of XP won't be as great but it will still be significant so that all the characters are competent.
Make your case for the option you'd like in the comments below.
