I didn't see the NET part... In the N2, coils might gunk quickly (the 0.7 will probably have the best life). Are you up for an RTA yet? If you are there are several nice choices in the MTL category. The hussar Coppervape clone is a great tank, you want the MTL version from FT (it will come with an airflow reducer.) This was my first build, and it's a very nice tank with various options for sizing. The build deck you'd want would be the single post build deck, it's large and easy to build on. There's also the Doggystyle (again most folks agree the clone is pretty good) one of the Kayfun clones, possibly or perhaps the Vandy Vape Bereserker or the Siren V2. They all get good reviews.
If you want a tank to run your NETs in, I really like the Nicolas Vapefly tank, it's a slightly sub0hm MTL tank. I find it to be a great little tank (and it is genuinely MTL, even with the 0.6 coil, the vape still pools in your mouth) it also comes with a 1.8 coil, coils are inexpensive, can be rebuilt if desired, but they get long life. I had my 0.6 coil in steady rotation for about a month and had not something happened to my mod to torch it, I think that coil would have continued going strong for a while more.... And I used it daily. It's really a fantastic tank in my opinion, especially if you have gunking factors (I do, high VG) the coils are great, they can be rinsed and re-used once, and it's just overall a great MTL tank that can also do restricted lung hits if desired. I like both coils, and I really like the vape, it's not an expensive tank either. For NETs, I would really recommend it.
Best of luck,
Anna
