Pulp, I may be alone with this opinion, but I prefer the faster play of the STB. I hope Maurizio is not just doing just this run for me though - the Giulia is pretty much perfect as you say. I like the larger size for show, but like the smaller shape for speed. If it were my project, for the next run I would go for a size somewhere in between the two.
I would like to see a second tip shape, a bearing tip something like Spintastic's shape with a flat shelf. I've found it is very hard to do upside down tricks with the shape I designed. I still believe that if a top is to be convertible from fixed to bearing, it must work as a fixed tip first and foremost, but the shelf has advantages for bearing play.
I love all of Maurizio's projects, what I would like to see the most (but I know the challenges) would be a 1WB Giulia. I think it would be pretty cool for S8 to be the first to do a production run with that feature.
