Split the Warhounds.
Get air cover. As a minimum two hunters or 2 thunderbolts.
Get the 'odd' razorbacks.
If you want a different BTS consider a Reaver, sucks vs guard, but good against most else.
And I really think the marine SC should come down to 75 points now he doesn't get leader twice.
To fund all this I would drop the Devs, replace them with the Warhound singles, leaving 250 points free, drop the librarian as devs that aren't being air inserted rarely need him, 300 points free, get two razors and two hunters leaving you 100 points for either another hunter or some other re jigging to get some scouts or similar.
Alternatively drop the devs and the librarian, buy a third warhound, have three singles and get the razorback. Still no air cover though
Could keep the warhound pack and then have enough for a hunter instead of a razor.You can convert rhinos to razors fairly easily incidentally. Bit harder for hunters but not to hard (use some model aircraft missiles?).
And Fluff wise I would point out space wolves are anti teleporting, maybe consider meching the terminators (which really needs to cost 650 points, though it seems I am the only person to playtest this lots!)?
