Your room looks very nice Stymie, I personally believe our room benefited with the addition of the Tri-Traps along with an acoustic panel behind the center channel.
Where our TV is located the floor to ceiling height is only a little over 7 feet so therefore I carefully cut a pair of the Tri-Traps and fit them on top of another pair for a floor-to-ceiling application ... I thought it looked much better than the freestanding four footers and it wasn't that big of a project, although Glen doesn't advocate this method.

Prior to cutting the two pairs to fit the full length corners our were freestanding in the corners as was suggested by Glen along with having a second set placed on the floor beside the corner traps either along the front wall or the side walls.
