I contacted the OP on the thread you gave me. He is not sellling it because he said that it is too fragile. He said he cant even put it in his pocket b/c it will break
Yes. The Y-Tip makes the unit very long, and it would not fit in a pocket very easily. You could very easily snap the tip or atty's off. While it works perfectly I would not feel comfortable making a buck on something that isn't bulletproof.
The Y-tip I made has ZERO leaks, so I am inhaling directly off both atomizers, but the draw is still too weak. I thought it would be the answer, but it wasn't. Even if a fancy Y-Tip is made, it still won't solve your issue. Your lips seal ALOT better then you think. It just feels like your getting air in from around your lips, but it's actually the air from the atomizers. I actually don't use the y-tip because it makes ZERO difference on the amount of air and vapor I get.
I recommend Covering half of the air holes on the atomizers. Just put some tape over half of the spot where the atty meets the DBSB top. You can try this by just putting a finger over half of the connector while you inhale.
You could also alternately use some restricting thread adapters.
**Be careful as less air flow through an atty will cause it to generate more heat by the reduction in "cooling" air flow through it.**
I personally use two of the longer 510/901 delrin drip tips on the DBSB. I place the tips on the side of my mouth, not on the middle of my lips. One tip almost touches where my upper lip meets the bottom, and the other is slightly off-center. Two flat 901 tips in this position work pretty good as well.
I have a couple more ideas, I'll see what I can come up with.
