@corelli: Thanks for the guidance on considering Soundcity Outriggers. I've read the entire thread a few times now : ) and I did bookmark their site. I've had my eye on Sistrum for years now, but the cost is higher and I'm concerned about tip-over using them. Soundcity and their multiple configurations may just be what the tip-over doctor ordered....
During my previous reading of the thread, I didn't get a feel IF and by HOW MUCH each owner preferred the final option they went with vs the stock spikes (with the exception of Sistrum). I'm curious about this. If there aren't significant differences then that would be good to know as well.
I'm thinking of using Herbie's sliders under the rubber feet, vs going with wheel casters. Thoughts?
