Space Wolves 2000pt

I've been playing around with army builder and I put together this list. I am trying to work up a list for next year. I would appreciate any tips or thoughts on what I am doing right or wrong. My goal is a list that is both fun & competitive. Here's my first pass:

My basic plan is to have the Long Fangs camp the backfiled and shoot at vehicles/units. Terminator Wolfguard & Njal will ride in the Land Raider and assualt forward suported by the thunder wolves. Grey Hunters will follow in their wake to capture objectives.

Wolfguard in Power armor are attached to grey hunters so they can add close sombat support and use their shields to soak invul saves. Thunder wolves are 3 separate units so they cannot be targeted as a group with shooting, but can stay near each other to support one another and counter assualt.

So is this any good?

I learned my lesson with taking units of one thunder cav. They were shoot off the board way too easily. I'd take one unit of three.

The only thing that stands out to me is that you are not using the free special weapons on the grey hunters. You have just got the one meltagun.

1. You're burning a lot of points in that Wolf Guard unit, especially w/ Arjac. They're a big target and the raider will usually pop before you want it to.

2. By taking wolves you give up Combat Squads, so your 10 man units are stuck at 10-man. You may be better served w/ 4 5-mans.

3. I like single TWC. You want them to get shot to hell. Any AT fire into them is fire drawn away from your rhinos. I'd rather see them all w/ Wolf Claws or Fists though.
