Final list I think. Trying to squeeze as much shooting into list mindful of the highlander comp.
HQ:
Librarian
Troop:
10 Man Tac Squad - melta gun, combimelta, missle launcher, razorback, assault cannon
10 Man Tac Squad - melta gun, combimelta, heavy flamer, rhino

9 Death Company - power fist, (edit - jump packs)
Fast:
Bike Squad - 2 gravguns, combigrav
5 Assault Marines - 2 melta guns, combimelta, drop pod
Heavy:
Baal Pred - assault cannon, heavy bolters

Total points 1250
Gives me mobility. As well as lots of special and heavy weapons. List also has a nice close combat punch.
