Im looking to get a new piece, looking for either Mobius or Sovereignty. Ive been looking at videos to see which id prefer, but still not sure and need some advice or opinions. I reeeeeaaally want a Mobius 60mm stereo matrix, but im worried at only 14"inches tall, it'll stack nice and high and get water in my mouth. But I dont want that to deter me from getting a stereo matrix. Would it be worth the extra $60 for the 65mm stereo matrix? And as for sovereignty, I would want a king stemline, but im not sure the difference between the up grid and down grid. Which is smooth and stacks better? Give me some input if you can and I appreciate all of your guys help.
