Hmm, I'm not sure about this list.
Who are are specialists and what traits are they going for?
If you have a heavy weapons guy I would almost always suggest he be your Indomitable specialist (going for relentless so you can at least move up the board).
I used to have snipers in my kill team, and even tried out a full sniper scout list for fun. BS3 hurts, especially when you have so few models. And then you are always relying on a 50:50 chance to wound even against grots! I was rundown by an gretchin horde with my all sniper scout list as I couldn't wound the buggers! By all means take them if you want, but I certainly wouldn't recommend them
