Someone I know has brought back a Bhutanse bow, via the archery event in Korea I think.
Initial testing shows an average arrow speed of 186fps, a top speed of 194fps. ~The bow is the typical two bits of bamboo bound together at the handle, Bow draw weight at the draw length being used is estimated at 50-55lbs. Arrows used appear to be failry standard field arrows. If I can get permission and actually ge thold of some pics I'll post them.
Though this may be of interest.
