I believe I have found an excellent item to help with small-footprint / very tall stands: a 21 lb rubber plate made for securing pop-up tent canopies. The 2.5 in slot will fit nicely around vertical stand poles, and with the whole thing being made of rubber it should stay in place nicely.
Rolo mentioned weights from a zip-up shelter for his new stand. I wonder if he is using something like this?
You can buy direct from the
manufacturer, but shipping costs are exorbitant. Instead,
this eBay seller is much cheaper when you factor in that they offer free shipping, and nice small-volume discounts. 84 lbs of these plates for just over $100 US seems like a good deal to me.
I am going to get one of these to use on my small stand base.
