Sounds like a nice pairing you have went for
The 2.5 is a lot more customisable which will give you more options.
Be sure to let me know how you get on with it.
I've used it for nearly a week now and I really like it. Easy to set up , great flavour and the airflow is genius, gives a really smooth, thick vape. Only negative is how huge it is, an rda the size of a medium sized rta, but very much a price worth paying.
