I'm currently a Smokeless Image customer. I believe they exclusively use the 808d threading (batts are male and clearos/cartos are female)? I've been wanting to step up to VV Spinner batts and they are about to start offering them, so I'd like to stick with them so I don't have to buy everything new (cartos, clearos, ect.). But I'm not totally happy with any of the clearo's/tanks I've tried. I'd like to try out VapeDudes Texas Tuff tanks, but was wondering if SI's cartos will work? I know I'll have to punch them myself, and can't imagine any reason they wouldn't work other than the connection itself. The Boge cartos the tanks come with are 501(?) male thread, and the threads are all that stick out of the bottom of the tanks when assembled. Both the Boge and SI cartos are 35mm. Does that mean the overall length of both brands is 35 mm, and therefore the SI cartos would be long enough to fully seat in the tank and have enough length to connect to the batt leaving the air holes open? Has anyone tried this?
