eVod and Protank heads are so cheap that I'm having thoughts of discarding them after 2 weeks or so (I've had some T3 heads going for 3 months now, rewicked). At 7 bucks the 5 heads I don't think it's worth rewicking or recoiling them anymore. Not so about Vapeonly BCC, those cost double for 5 heads. I'll just clean them with hot water, or leave them in vodka overnight but discard them after 2 weeks. No more dry burning or babying heads anymore.
