1. The screen is significantly larger than the inner diameter of the GVG chamber, so it has to be carefully formed into a bowl-like shape – almost a hemisphere. I put the screen in the chamber like a right side up bowl. It might work better (less glass contact) if put in like an upside down bowl.
Upside down won't work better, DMT will make it to the glass at the edge of the screen and run down the side. Are you positioning the screen just below the filter top or further down? Because there's hardly any glass contact the way I have it.

2. I tried only 15mg, and when melted, DMT does cling to it quite well. However, the DMT forms a solid film over the surface with no air gaps. Prior to vaporization, air has to flow around the “blot” of melted DMT. The result seems to be slower vaporization.
I did not experience slower vaporization compared to using copper mesh. I don't pre-melt with the titanium screen, since there's no need. Seems like you pre-melted, leading to the "blot" of DMT and possibly more restricted airflow? Could also just be due to a difference in our standard techniques.

3. I always inhale gently and slowly, but my guess is that if one were to inhale too forcefully, the DMT would be pulled/sucked off the screen and would drip.
I tried inhaling faster than normal and didn't get any drips. What I got was increased condensation in the pipe. Maybe if I had pre-melted, drips would have occurred? I'm sure there is some point at which the force of suction will cause drips, just as it would with copper mesh.

4. I haven’t noticed any leakage, so I think it is more effective than screens made from polished wire.
This is key. Leakage was my major concern when I got the screen. None seen.
Re the pros: I believe there are more than two pros. Just my opinion.
Re the cons:

>> Expensive when compared to copper ribbon. The screen + postage was over $13. For that amount, one could purchase enough copper ribbon for hundreds of ribbon discs.
Agreed.

>> Vaporization seems slower. Maybe this is due to the restriction of airflow around the film of liquid DMT? Even with a small dose of 15mg, vaporization seemed to take noticeably longer than it does with 25mg on a copper ribbon disc.
In my experience, vaporization is not slower.

>> Getting the screen to just the right shape to fit in the GVG is tedious. In the time it took to shape the screen, I could have made 3 or 4 copper ribbon discs.
It was less than 5 minutes of tedium for me. When you add up the time it takes to form the copper discs to the right size and density, then clean with acetone and evaporate, it's a wash. An added benefit of the titanium screen is it will last a lot longer than copper discs.

>> Limit to how much DMT it can effectively hold. 15mg when melted spread out over maybe 1/3 of the surface. A large dose of 40-50mg (larger than I’d ever need) might drip off. A copper ribbon disc can easily hold 100mg + without dripping.
Agreed, there's definitely a limit, and copper discs can hold much more. I've done 30mg with no leakage. 50mg+ might be too much for one screen. Any volunteers want to put this to the test?

I think the titanium screen might actually be more forgiving when it comes to technique. But my newbie days are long gone and I can't really be objective. It would be interesting to see if a complete newbie would find it easier to deal with this screen or a copper disc.
