I just ordered a Vaporshark DNA30 and now I need a new topper. I have a kayfun, Patriot and carto tanks but I want something small. The vaporshark is .7" thick and that's just a hair under 18mm. I'd like a couple toppers that will sit flush and not overhang. I'm about to travel overseas for the next 3 months and this will be the perfect setup. So, my question is what rebuildable toppers are out there that have a diameter less than 18mm? tank or dripper I don't care. If you have pics with the topper on a vapor shark please post it. Thanks.
