Does anyone have one of these packs from Misco? Just got mine today and I can't beleive the weight of the mount... it makes the EX530's I put up a few months ago seem like feathers compared.

The board is going in a junior classroom so the board is quite low... how much higher does the boom have to be to work or is it a set height..? The teacher wants the board quite low so I can't have the boom at the top of the board or they will bang their heads

Oh well.. off for a leavers party tonight to cheer me up.
