I haven't used the boards, but I believe that the takoon curver will be better. The switcher was shaped by Franz Olry, who is now shaping the curver in TAKOON. The Curver is a more modern design, and I believe is stronger, looks better, and probably rides better. I HAVE seen the curver, and was impressed by the costruction, it has a polycarbonate outer skin, with the graphics printed on it, very similar to the bic sport boards. If you want to see some pictures of the curver, look in the "takoon c" folder at this address:
I think the construction of the wipika switcher is that of all big production boards, and that the paint chips off, and it is overall a weaker board.
