IMO: The tradition materials (horn/silk/sinew) are also resistant to creep at some degree. 
sissara, you will be surprised to see that you're wrong... Try do do some test using the chronograph, you will notice important variations in speed - shooting the normal way or doing that "snap shooting". Ginni can tell you more about this. This is more visible during summer time, when the bow loses power after being shot in very warm weather conditions.
so, the question is: can you break a korean bow using it at low temperatures? I mean below 0C.
The temperature here is about -14 right now, very mild weather compared to last week 
the twist of the bow handle comes from the correct handle grip. First, your left hand keeps the bow grip with the thumb oriented upwards, so that the thumb aligns with the upper limb, then you align your index finger with the left side of the upper limb, then you grip the handle with your pinky like holding an egg. This is how you must keep the bow handle, the twist being a result of the position of your hand on the grip. It is easier to achieve the same twist every time by keeping the handle the same way than trying to guess which is the right amount of twist when randomly positioning your hand on the grip everytime you shoot an arrow.

Ok, some of you made a confusion, Mr. Yeochang Yun invited us to see the archery range. The person in the pictures above is Mr. Er, and he indeed uses 70lbs bows and his draw is about 33.5", Mr. Yeochang Yun uses a Songmugung bow of 45lbs and 32" arrows, if I remember correctly.
This is a bow made by Mr. Park from Songmugung. It is the usual hwarang bow made with bamboo core, carbon on the back and belly, and instead of black paper pulp it had a stripe of bamboo. The release feels much cleaner than the classic model of hwarang bow. The shape seems to be closer to the horn bow, the bow keeps its shape after being shot, if the pressure on the handle is not distributed equally.
Tawfiq,
I have a few korean bows, Songmugung and Yeonmugung and I want to show you some pictures. This Yeonmugung bow is marked as 45# @ 28" but I weighted the bow and the scale shows 48# @ 28". When I draw this bow the limbs become almost parallel, but I feel the bow starts to stack only at 34.5", and the bow is the shortest model form Yeonmugung.
here is Ginni drawing his semi-hornbow from Songmugung, 74# @ 28"
also, here is my 66# @ 28" Yeonmugung, janggung- the longest version made by the bowyer, also can be drawn to 34", and the stacking feeling appears after 33"...

yes, thanks for asking, I also sent an e-mail to the admin
Last month we have the chance to visit Mu Deok Jung in Daejeon, thanks to Mechwar and his friend. The athmosphere seemed to be magical, this place is like no other in the whole world! ))
