I got both Badab books this week as a gift and after nerd raging for a bit I decided on making a small Astral Claws force, (the color scheme is great and I love the FW shoulder pads) now the question is do I use the SM codex and 1 or 2 HQs from the Badab book or full Tyrant's Legion? Is a Tyrant's Legion list viable and effective in 6th edition? Also what chapter tactics? Considering they are either of Ultramarine or Dark Angel decent I guess I'm stuck with Ultramarines. Let me know what you guys think! Thanks all!
