Let\'s assume this crystal has flexibility then shall we? Whether it be by means natural or magical.
Yes. I\'d prefer the non-magical way, because otherwise almost nobody would ever possess such a bow.

I cannot argue about the bows, but I have seen crossbows fashioned from metal that is not very flexible, and it has more power than most bows, able to punch a hole through platemail at distance.
There are bows that aren\'t very flexible as well, the important thing isn\'t the ease of bending, but the properties of the material itself. You can make a spring that can be bent only by extreme forces, but it still is flexible (flexibility means that it will bend, not break, like an iron bar vs. a bar of granite). Something with flexibility may or may not have tensile strength (i.e., it may try to regain it\'s original form, or it may just stay the way you bent it). Something without flexibility, however, cannot have any tensile strength, because it\'ll just break.
Just look at the springs that are being used for cars. You\'ll not be able to bend them any significant distance by your hands, but if you use a motor or lever forces (as in crossbows) to bend it, it\'s tensile strength can be converted into extremely high power for the projectile. This is the way both crossbows and normal bows operate. Crossbows, however, are more easy to use because you don\'t need to hold the string in position yourself, this is done by some metal pin. Therefore, you can make it\'s tensile strength way greater, because you don\'t need to hold it. Also, there are bows (english longbows and modern bows with special mechanics) that can also pierce platemail. In fact, the arrows can even penetrate the metal reinforcement bars of buildings (I know of one arrow that still is stuck in such an H-bar)!

Also, I thought All bows were symmetrical? Or else they\'d not work.
Yes, I was referring to the string. If the tensile strength came from it, it needs to contract absolutely symmetrical to allow for precise firing. The bows need to be symmetrical, as well, but this is more easily achieved than with the string. Sorry for not being precise.
