One of the many things that Rick and Maria mentioned during the CZT seminar I attended in May 2010 is that no tangle is any more complicated than any other tangle, but there are certainly tangles that require more concentration. Anything is possible, one stroke at a time, right? I think this is one of those tangles that requires more concentration. It also looks nice if there's a large area of it.
On the tile below you can see Bevia in the upper left.
Tangles: BEVIA, Florez, Pearlz, Umble, W2, Yincut and Oakling (a tangle I haven't shared yet.)
