I wouldn't. Generally you want to just to do one light roll a day outside of events. When an event (with an event banner) starts, do 3 rolls a day in the event banner until you have the ships you want, then switch to 3 light rolls a day. That way you still get the event currency (for the "build 3 ships" daily mission) to spend in the event shop.

The upcoming French event rerun is pretty decent if you're new (less so if you have a bunch of URs already). Pretty good battleship and healing carrier in it. You're short on backliners so spend the cubes on Clemenceau and Painleve.

If you must roll now, consider the heavy pool.
