I'm planning on getting either an SVD or a Provari here soon (probably Provari) and I think I'm going to switch fron Kanger tanks to carto tanks along with it. From what I've gathered, the J tanks are wonderful, but most of those threads and reviews are older. Now I see a lot of people praising the ibtanked lineup. Aesthetically, I think the J tank looks better, but performance is obviously more important. Is this a different strokes for different folks matter, or is there a clear winner between the two?
