Satern, Alexander, or Group Buy?

I don't have numbers in front of me, but, how much difference in weight will the monster 16" be to an AA-plus-the-thread-adapter? Plus, the AA will have comparatively more wt at the tip, which will mean more barrel whip under fire and possibly more POI change from the suppressor (although if constant that POI shift is just an adjustment to make). I think I would rather have a more std barrel profile for mounting my suppressor....
Just a thought.
