@twoleftears’ suggestion is a good one. Use the Herbies until you find your permanent (ha!) speaker placement, then if you want remove them and install the footers of your choice. You can try the current rage---springs---without (heh) springing for the Townshend Seismic products. If you like what they do, start saving for the latter!
By the way, if you think moving around the 3.7i is hard, try a Tympani 3-panel model! Grant Mye makes a stand for the Tympani's, but they're not cheap.
