A major plus for Mobius pieces (IMO) is their lack of drag.
It makes the whole hit
feel different.
Even on pieces that didn't have much drag, they just don't compare to the smooth ease of a rip from my matrix...
I haven't tried a BL Saxo yet, but while I do think BL make pretty good stuff for the price, I'd guess it has more drag than the Moby...
Poopmachine,
If you are going to get a stereo matrix, make sure you know what you want, there a few variants floating around out there.
1 - 60mm vs 65mm: the bubbler mouthpiece version is only available in 65mm AFAIK (the 65b) the tube mouthpiece is available for both (the 60t & 65t)
2 - Slitted Disk vs Solid disc: the stereo matrix has a disk between the 2 matrix percs. this forces the air to go in the bottom one, and out the top one.
On the earlier models the disk was a solid ring of glass, which meant that the water level would rise a bit after the first hit. so at some point they started adding slits to that ring. some air can then escape the stereo matrix and go up the slits, but the water will stay the same after each hit.

I'm not sure if they still do one, the other, or both, but it's something to take note of.
3 - (this one is fairly obvious
) DI joint vs Regular: I've seen both out there
