At 0.5Ω of resistance you're pushing 7.4 amps and a whopping 27.38 watts...
If you did that to an eGo, it would destroy a small village.
Let me start off by saying I'm a dct carto tank guy. I vape a strong cinnamon juice and even add some cinnamon oil to my remade cinnacide.
If you intend on using a cinnamon juice then I would go with a dct carto tank, just pull out the drip tip..twist the tank up a bit and refil.
I now love my Protank 2's, both the full size and mini, but to refill you will need to remove them from your PV and unscrew the bottom portion then fill and place back on the PV.
If your not going to do the cinnamon or other juices that will etch/melt/crack and weaken polycarbonate tanks then I would suggest the iclear 16. Great vape and just unscrew the top portion and fill, no need to remove anything.
Those are the least expensive options. There are other more expensive options that are smaller and made of Pyrex or polypropylene and are easy to use as well. Like the vivis etc.
I may have a record for being a member the longest time without posting-2009. One of the reasons is numbness in my hands. I drop everything. In spite of this I do build coils and spend a great deal of time searching for and retrieving dropped screws, etc. I just got the Russian 91% and I love it. To answer your question, I think the Protank 2 is pretty easy, and is glass. As far as juice, for me it has been trial and error. There are great ones and many not so great. I have bought no less than 500 bottles over the last four years.
I love micro coils. I have real dexterity problems and it is frustrating. I did get a magnifier/light and it is great for rebuilding. I agree about the needle nose, paper clip, for me a tiny screwdriver, and of course my torch.
Have you tried the Davide? It has Kanger style heads and is easily fillable from the bottom with two holes for ease of filling.
The Kanger Unitank is a bottom-coil clearo that fill from the top, like a Vivi Nova. It's currently in plastic, but will probably be available in glass soon (or something just like it). Smoktech makes a Vivi Nova in glass.
I've also seen some "Hypertanks" available at a local vape shop. Looks like a hybrid between a DCT tank and a Protank. I think they're glass but I haven't actually looked at one closely.
