Gas Block Options

[Razorhunter]

I would like to find out what gas block options there are for AR10's, other than the norm?
What gas block would you guys use on your AR10 dream build? Are the adjustable gas blocks from Armalite (and soon from Noveske) strictly for suppressed use? Are they really even beneficial for suppressed use?
I am trying to determine what gas block to go with, and if there is reason to go with anything other than a regular low pro gas block.
Do you guys prefer a lowpro gas block UNDER the handrail, or do you prefer something nice looking, that is out in front of the rail???
What would you guys use?

personally on my ar-15 i use a gas block that sits outside rails so ease of access it there plus
it is more than just for a CAN u can tune if you will different loads and shut it off

there are three notches on mine on-full on-.678 for a different load and off for single shot only
