Space Wolf 1850pts

So after getting some very helpful advice from a few space wolf players I redid a list for 1500pts. It works very well and now I am scaling up to 1850, so I thought I would throw my list up and take some wisdom from my more experienced brethren, so fell free to comment.

note: if my points are off or any other error I apologize for being human and making mistakes

Long Fangs x6 215pts - Missile Launchers, Razor Back with Twin-linked Lascannon

This list is very different from my 1500pts list but I think it will do fine, However I am lacking a few missile launchers at the moment so I figure until I get them if I want to play 1850 I can just sub out a long fang unit for a Lascannon Predator what do you think?
