Y'know I kinda feel like asking the community what I should take.
SHould I take:
1) My Grey Knights. Probably like two full strike squads, Coteaz, some purifiers in a Redeemer, maybe some cultists with razorbacks on the side. Good old fashioned 5th ed stuff. I think it will smash other Marines if I can catch them, but might be outgunned at the 24" range by some lists (cuz GK are expensive, yo) and it will also have like no long range to sepak of. But I have all the models and I miss playing them, they're pretty.
2) Bike GK-ish guys. I actually have Grey Knights on bikes, which look pretty bad compared to what I can paint now, but I still love 'em, cuz f'U, they're GK on bikes, and I think that's awesome. I would be building some others to be more normal bikes, the GK guys might become a command squad.
3) Borrow my friends Black templar guys, and seriously put like 70 marine bodies on the table. I am never likely to play that otherwise, and I think it could be awesome. (Jared would enjoy shooting them up with his plasma bomb, I think too)
