Here in Denmark and many other contries, we have to use EFRA approved pipes http://news.efra.ws/fileadmin/news/2...of%20March.pdf

If the 9901 haven't got enough bottom, the new Novarossi 2084 should do the trick.

I had read, that the re-10 pipe should be similar to the Ninja 2042 and re-11 is a copy of Axe Rossi 2050 (thanks Neobart )
