Thank you all for the welcome. I've read various conflicting reports on some of the recommended places on this thread for base liquid so I'm not sure which direction to go in. I like the base from Make my Vape. It's clean and does not cause any issues. It's just a bit too expensive in comparison to others I have looked at. I've tried others in the past but they have never proved to be as problem free. Following my original post, I have given a German brand called Avoria a go. I've made a couple of bottles up with my usual juices so I will see how they pan out and report back.
