Javier has made a correction to the initial specs: the weight of the top is 65 gr, not 55 gr. However, in the future he wants to lower it to that range or even less.
If I understood correctly, something he is not too happy about in the current model is the connection with the tip: because the way the body is made the wall has a round edge and that leaves a small groove. But on an email he tells me he has visited a new factory that can do advanced metal spinning ("repujado") and this will allow him to do things that seemed impossible a week ago. Trompo Space should be praised for opening new frontiers in the manufacture of tops.
