|I hope that someone who has experience with this setup can tell you something about this setup.
Anyhow, most rollerskaters in this forum ride on self-built skates. You can find information on how to do this on this site and I'm sure anyone who has built some skates her is willing to give you hints and tips.
Another option is to have a setup built. At least Gambin in Spain offers this service and maybe I could talk at least one other person into doing it.
