I'm still undecided about it, but I did remeber reading in a Sure Bert thread about giving high VG liquids a shake because the flavors seperate. It does seem to make it more consistent if I give it a shake before I squonk. I'm limping along on my last bit of RxW that's a few weeks old and I don't think it's working quite right so I'll give this stuff another try when I get some new wick next week.
