Agreed on the power issue, get as much power as you can afford, you don't have to use it all just yet. Commercial tanks don't do it for me, it took a Kayfun 3.1 clone and a SVD to get me off the stinkies, but... there wasn't a Nautilus Mini then.Welcome @Evolutionary
Congrats on joining the forum - I am sure you will find many ways to improve your vaping experience.
All the best for your journey. Enjoy the forum.
As for your question on a good combo, there are many, but I can vouch for the Nautilus Mini (with the new BVC coils) as a great standard tank. Probably a good idea to get a higher powered mod for it - something that can go up to 20W - and will double up as a good mod if you go the rebuildable route later.
As for getting a stronger vape - you will probably find more luck going the rebuildable route.
From the devices I've tried, I like the REO the best. Awesome flavour, strong throat hit, simple and reliable.
