I'm sure you'll like the VaporKing device itself. I hope the low cartridge strength cut's it for you though. It's been 12 days for me since I've had an analog and I'm feeling great. But I use the 36er's. I never considered anything lower and my flavor options on carts are limited to only what is available in the 36'ers. I smoked two packs a day and in the end I was ordering Winstons from the Ukraine because they cost $1.33 a pack, were much stronger than domestic Winstons and didn't have the crap they spray on them to make them "fire safe". Because of all that, I'm probably not the best person to give advice to an ultra light smoker. I just hope that what you do order is strong enough to overcome your analog desires.
Good luck and Cheers!
