I've found that 306's like a lot more juice than 510's. Where I'd normally drip about 3 drops in a 510, I'd drip 4-5 drops in a 306 without flooding it, and just drip 2-3 more when the flavor drops off.
agree 100%....especially the ones w/o primer....letting the juice absorb first then feeding more = no burnt taste...


that's really nice of you.
My husband just went out to buy himself a birthday gift today, so now it's time for some serious testing.
