Just a quick note.  Used Danger Den tubing exclusively on the BlaakHaart because i wanted colored tubing and I hate Feser tubing.  It was an unknown quantity going in, but...
Best damned tubing I think I've ever worked with - NO HASSLES with any turns or any connections.  the matching Kerby clamps are kinda cool too 
 
The tubing cutter that comes with the kit is a little lame, I used my Home Depot special cause the DD one is so small.
3 meters w 10 clamps and tubing cutter = $29 and change, about the same as Tygon 3603.
