imho, there are many things to consider about 'longbows'.
for the most part and for all their outward simplicity, longbows are far more difficult to design and properly build than one of those 'wired wheel' type 'bows'.
just like acoustic flat top guitars, longbows are ALL unique in one way or another. even within the same brand and model. things crafted from copious amounts of organic material (wood!) are just that way,
there are significant differences between 'hill-style', 'mild r/d' and 'aggressive r/d' longbows. significant. the differences are manifested mostly in overall performance and the 'feel of the shot'.
