slaw, millercarbon,
I have the Origin Live belt on my TT and thought well enough of it not to send it back. The talc suggestion did nothing but cause the belt to slip and create a bit of a mess to have to clean up but next time I need another belt, I'll likely get the OL again.
As far as controversy about decoupling the cartridge from the headshell, I'm not sure why a controversy exists. The product either works, or it doesn't, or it makes things worse.
