@The Beagle - Just to be a bit contrary, I prefer the Ti Woody because it doesn't have that add on mouthpiece! LOL We are indeed many and varied. haha
To me, the MP looks added on. I find the Ti Woody double crown to be simple, stylish, and sleek. I never noticed the end feeling cold to my lips but...dang, I bet I notice the next time. LOL
I also have recently put my Ti Woody into a Delta 3D Studio's 'Nearly Universal Vape to Waterpipe Adapter (in Medium) I love the Nearly Universal part hehe. I do love
@Ratchett's stuff and this SONG (silicone to glass) adapter worked wonderfully with my water tools.

I personally do not like the ceramic screens. I broke mine straight away. Two things to do:
1) get one of those small concave Ti screens that every head shop and online retailer seems to carry. They are primarily used, I believe, as screens in the bottom bong slide bowls. Fits in there perfectly. Make sure to keep the little C clip that holds the ceramic screen in place. Put this in after the new Ti screen and all is good.
2) Ask George/Matt for an OG CCD (thin Ti screen that is used with OG). Again, be sure to keep the C clip. Just press the Ti screen into place (which something like the blunt end of a pencil or chopstick) and pop the C clip in. I don't think the C clip is needed with the CCD, but I like the extra security (false or otherwise haha)
I have never used an Omni so I can't tell you anything about them.
If you get a Ti Woody of some sort (or Omni), think about springing for another $35 and get an OG also. You will find it money well spent.
Cheers
