Yeah that makes sense. With certain juices (Anarchist juice is terrible for this) after about 2 days my RDA's taste like I'm vaping through a rusty exhaust pipe, while the same juice seems like it's ok in my RTA's for a lot longer than that. I've had Anarchist red in my Gear RTA for over a week, it needs re-wicking today. As an extra bonus I'm also finding that juices which are too sickly for my drippers vape really well in more airy RTA's. I've always gone for maximum flavour but sometimes that over-saturated flavour is too much. I'm burning through my stock of sickly juices and they all taste really good in my Peacemaker RTA with the airflow wide open. Live and learn..
