1500 Space Wolf Tourney

Looking at the SW book I think I can make a better variant of my 1500 SM tourney force with this book (ironic yes?). Again voicing my dislike for 1500!

HQ –
Rune Priest w/Saga of the Beastslayer and Chooser of the Slain
Powers: Tempest (or Murderous Hurricane) and Living Lightning

Elites –
Dreadnought w/2x twin-linked autocannons

Dreadnought w/2x twin-linked autocannons

Troops –
10x Grey Hunters w/flamer, meltagun and Rhino

10x Grey Hunters w/flamer, meltagun and Rhino

5x Grey Hunters w/flamer and Rhino

5x Imperial Storm Troopers w/2x meltaguns

Fast Attack –
2x Land Speeders w/Heavy Flamer and Multi-Melta

2x Land Speeders w/Heavy Flamer and Multi-Melta

Heavy Support –
Predator w/Heavy Bolter sponsons

Predator w/Heavy Bolter sponsons

3x Long Fangs w/2 missile launchers and Rhino

1470 pts
12 armoured behemoths
34 infantry

30 points to play with. Essentially I've only lost out in my Fast Attack (losing 2 speeders) but gained or stayed the same in the other slots whilst increasing my points in Troops (apparently a "balanced" army is 40-50% troops with no uber units which can take on any type of force...how does one do that with 50% in troops...?).
