I go through phases in my bow making, straight limb over build bows at first, slender bows, almost all backed with snake skins, bamboo backed bows, slender straight limb bows with none backed with snake skins and my current phase of unbacked static recurves. My choices have nothing to do with performance, I just make what I find appealing at the time and have kept things interesting for the last 27 years, I always want to be learning something different to advance the craft.
My best shooting bow to date is a static recurve, could be the design or it could be all the experience I have gained over the years going into that particular bow.
