Noise marines and sonic weapons- army viability

[Blade_and_Honour]

So, I am close to finishing my plague army and want to take on a new project. So, I turned to the god of excess hoping to find my pleasures there.

 

I was hoping to run 6 units of noise marines, 2/3 with sonic blasters + blast masters then the rest of the units with CCW and the champ armed for close range (doom sirens). The HQs will be blackheart stand in and a lord (probably with lightning claw and brand) - this will be the core of the army

 

 

The only reservation I have is the effectiveness of this build. Will sonic weapons work as well as I hope. The army face a lot is tau and constantly come up against 3-2+ cover saves all over the place BUT will this build hold up against all comers? Any other things that i have overlooked under the lure of the god of excess?

 

Thanks B&H

Personally, I see two ways to run an effective noise marine unit:

 

5 Noise Marines: 4 Sonic Blasters: 107 points

 

or

 

5 Noise Marines: Bolters, 1 Blast Master: 125 points

 

Full squads of 10 are going to run you over 300 points when fully equipped, which is a significant investment, especially when compared to other units that are probably going to be more effective for the points.
