Okay. Soooooo... with a NON VV battery, it is okay to use the LR? I am asking because I have both kinds, and I have the 3 heads that came with the Vivi Nova kits. The way I originally read the chart (about one month ago) was thus: the lower the battery output, the lower the ohms should be. Getting sleepy just writing about ohms. Reminds me of college Physics. snooze
