GW Fun Senario SM Assault list

Hi, the local GW store is having a fun scenario game this Saturday. Here's what I know. Its 200 pts. of Assault Squads per player. Typically this would mean one squad but possibly two. I think they are doing model by model but not sure how this is going to work yet.

What I have:

So far I've built one five man squad of space marines. I'm working on another 5 man right now. To make things a little harder I've left my codex in Saskatoon so I've working a bit from memory and what I've picked up online. Any suggestions about composition and armaments? Again I know my opponents are bringing Assault but not what armies will be there. I think this is to show off the new Blood Angles Death Company and Guys with wings (name escapes me). So suggestions would be most helpful.

Thanks
James

P.S. Working on pre-heresy jump packs for this as well. Will post pictures when finished.
