I found a thread related to the topic, but I wanted specifically to ask if anyone does smoke both in the same pipe. I have dedicated pipes for Cavindish blends and latakia blends and have just started looking into Va/pers. I understand the aro/cav vs. "natural" tobacco dedication is important, but is it absolutely necessary to differentiate between VA and English briars? I'm sure if I stick with VA I'll end up dedicating pipes to it, but for now I don't know if I'll be smoking it in the future and it'd be simpler just to alternate between English and VA in the same pipes.
