Personally I use Single and keep the latency low. I think if you’re needing any more headroom then just increase the buffer. I did try double buffer for a while but any benefits were nulled by the double latency. I don’t have a super-PC/laptop but I don’t have any issues. Something to keep in mind also is that I believe in the 44xx builds Brad is working on Double buffer will be removed; https://community.cantabilesoftware.com/t/a-tiny-tale-of-woe-aka-what-happened-build-4400/11908
