A couple days ago I got a sheet of 500 ss. I originally got it to rebuild an RBA(that I lost one of the post screw on..grr...) and an IGO-L clone that's on it's way from FT. I decided to give it a go on one of myh protanks and I'm pretty pleased with the results. I think theres a noticable improvement in flavor as certain juices taste muted with the protanks compared to other delivery devices. For making them I'm just heating the mesh 2 times before it's rolled and 2 times after. I haven't been burning with water and juice, but perhaps I should.
I don't dry burn them like I do with silica. I found that I would pop the coil more often than not. I do check the ohms on my vamo, and it seems to vary until I start using it. I'm building mine with 4-5 wraps and getting between 1.7 - 2.2 ohms. The wick is hollow and so far no gurling or leaking. No flavor wicks. I'm probably going to add some cotton to the next build and see if that helps the flavor.
On a side note I'm also rebuild a vivi nova using only the 500 ss and the results are great. I much prefer the flavor of them. It's a shame because I really prefer the design and look of the protank.
It's also worth noting, I think, that I'm using 100% VG. Been on a Boba's/Gorilla juice kick lately
