Sand and shot?

Hello and thanks to all who have replied. I did go to Lowe's yesterday and purchased the play sand they had(only one I saw). I think I will forgo the lead shot at this time. These stands are not high dollar and I will probably replace them in the future. My next go round will have a mix of sand and shot. Nice thread on the cautions. Good listening, Bret

One point which has not been made here is that sand and lead have different absorptive/deadening properties which complement one another. I mix the sand and lead shot together and have found the combo to be very effective.

I have not completed building the stands so I may reconsider adding the shot. I'm also in need of some blu tack for the top plates. The stands come with foam pads but I rather use the blu tack. Anybody have a wad they would like to sell? Also what can I use that is similar that I can pickup at Lowe's. Ahh the pains of a phile :)

Use Blu-tack ONLY! The other "generic" stuff sold in hardware and office supply stores is CRAP...I had to find out the hard way.

I've tried lead and sand and have settled on concrete powder. It's extremely dense and dead for sound. Non toxic and plentiful/cheap.
