What's the difference between Mulberry and Tussah silk spinning fiber?

I spin my own yarn and have long thought about luxury fibers. SO I have a couple questions really.





First: Whats the difference between the kinds of silk? Any preferences?


Second: Does anyone prefer bamboo over silk? why? Why not?


Finally: I buy fiber from Paradisefibers.net. Does anyone have a better suggestion for roving?|||Tussah is the wild silk. They live out in the wild, in the jungles, and eat whatever they may find that they like out there. The silk may have a colour, depending on the source of leaves. Usually, the moths have left the cocoon, unless they are able to be harvested before they emerge.





Mulberry is cultivated silk. These worms are held in captivity, and are only fed mulberry leaves. The silk will be very white. The silk can be reeled off the cocoon, and will be very fine and very long.





Which is better? That is a personal preference. Each is still silk.





Bamboo is a synthetic produced from the pulp of bamboo plants. It may appear as silk, but has a slight different quality. It may have some colour to it as well. It doesn't handle quite the same as silk. It also seems to take a lot longer to dry.





Where to buy? There are numerous sources, depending where you live. I find that I get the nicest silk from http://www.treenwaysilks.com/ in Canada, but you may have a source closer to you that offers the same selection.
