I got an egg from kathy. and i absolutely love how it hits. The perc fires evenely. all the water bounces and bubbles up evenly, and its a very smooth hit.
I really really like how stevens egg looks. a lot. It has the mothership look to it. I really hope the neck is curved on it. I really like how it has a female joint, but wish it was 14 for my bucket. Or he should have a male fitting since it will mostly be used by oil people. As long as the glass isnt too thin, it shouldnt need reinforcement, but it might not be a bad idea.
The only complaint i have with kathy is it is too thin of glass. even if it didn't come broken, you can just feel the mouthpiece is thin.
By the looks of stevens egg, it looks like his top part is too big, or his holes or too low. needs to have more openings coming up the egg. Kathy's egg hits better, although it is smaller, it is better proportioned i feel, like a real MS, Where all the bubbles meet and break at the top of the inside hollow glass, and then go up the mouthpiece.
maybe he was just hitting it too hard and i couldn't tell. maybe the water level is a bit off. but just my thoughts
