This is my first attempt at Creating a Scout Army List for my own DIY 
SM Chapter. So please feel free to critique or rip apart. The first list contains all the models I own. I converted Vulkan and Cato.

 If the point costs decrease for the scout and Tactical Squads in the 6th Edition C:
SM coming later this year from the rumor mill and the addition to sky-fire missile much like the new C

A. Then that's what I'm going to add as well as the rumor of a dedicated transport for the scouts. The List below is an alt version where I drop the 5 man Sternguard unit for more scout bikes in which I can combat squad in the field.
