I love these two ships and have considered running them together in a list. Does anyone have any thoughts on a particular build for 100pts or is this just a bad idea all together?

Just make sure you check out SableGryphons post on Flying the Shuttle (Lambda 101 and 102) to make sure you know how to fly that thing (if you don't know already).
