Hey there,
I think this might be a lit to look at trying at low points games as it covers lots of the bases and give you the oppertunity to get to grips with the army. The list is a bit generic but it is decent.
The space wolves have many strengths but their special characters are not amoungst them
IMHO. Logan is a massive chunk of points that you could invest in more effective units... like a landraider, 2 troops choices or 2 full squads tooled out with missile launchers. Unless you are lacking the models don't take a character that eats up your points like that.
The long fangs can pump out lots of missiles which is great for anti-troop and anti-armour and if you want to try a different load out you can be surprised by how much damage 5 heavy bolters can do. They are one of the best support units in the game.
Wolf guard are a mandatory choice to bump the
Ld of your troops and to add some extra special +
CC weapons into a sqaud. For 29 points you can have a model striking with 2 attack(3 on charge) powerfist attacks with a combi-melta. They give you a second chance to pop armour with the combi-melta for those all important times you can't afford to fail and when they charge it's another 3 chances to tear open that can. You should stick one on each of the
GH and one on the wolf scouts to spread out their skills and equipment.
Mounted
GH in a rhino let you rush the board and lay out fire with the rune priest or the squad's melta guns depending on what you want to do. At least for the next 6 months this is a solid choice for troops (we'll see what 6th ed brings).
Wolf scouts are good for messing up the enemy and getting into their flank with melta guns, bombs and a decent combat squad.
