Fortunatelly i can buy "female fitting bowls" here too, so if i brake them, it's not a big problem
But i think i will look up someone, who can make me a longer and wider downstem, and than everything will be perfect
But it is really good now too. I think if i can, i will have made another endig for the upper part of the stem, a male style so i can connect normal bowls to it. I'm thinking on getting a small phunnel and a razan/nammor from the states.
