I have seen a few instances where a bowyer built a one-off heavy draw weight bow that did not perform well. I believe that this is because they are building something that falls outside their normal comfort zone, and they haven’t gone through nearly the same kind of development and lessons learned from building the usual 35-50 pound bows.
We find ways to become proficient at meeting whatever requirements we choose to focus on. For me, I am solely focused on building bows that provide maximum performance and durability only for flight archery. Everything else takes a back seat. So I do a majority of my testing shooting 5ggp or less arrows, and I tend to focus on heavier draw weights. These requirements drive my bow designs and build techniques and I eventually find ways to meet the challenge. But if I suddenly decided to shift my focus and build a 35 pound bow that was optimized for shooting heavy 15 ggp arrows at a long 32” draw length, then I would really struggle to come up with anything better than an average performing bow.
However, if we look at it purely from a technical design point of view, a heavier draw weight glass-composite design should outperform a lower draw weight design with identical ggp arrows and draw length.
