My SO is an iron worker as well. He's using an e-lvt with a Kanger Aerotank V2 with the stainless body. Judging from the scratch marks and dents, I'd say it's been kicked around a bit. (He actually just managed to dent the display last week.) He's had it just shy of 6 months and it still runs great. We finally upgraded him to this set up after he kept dropping eGos out his pocket from 20+. The rubber case on the lvt really helps it stay in your pocket.
Hope you find a good set up that works for you.
And remember: for a bigger, better erection - call your local ironworker.
