While this may be opinion-based, this question is specific enough to produce well-argued and specific answers.
The weight range for Goliaths is 280-340 lbs, or 127-154kg. Their height is between 7 and 8 feet, or 213-244cm approx. They seem to be all fairly well-built gigantic muscle-heads (more technically: high CON and STR scores).
I think Mariusz Pudzianowski, Strongman competition champion, is a good real-world comparison. Generally, his physique is similar to a Goliath (esp. Barbarian). Mr. Pudzianowski is 6'1" (185cm) and weighed approx. 320 lbs (145 kg) during his Strongman days. Despite being a foot shorter than the shortest Goliath, he lands in the 0.66 percentile of their starting weight distribution.
A max-size Goliath is 340lbs/8'0" = 42.5 lbs/foot. Mr. Pudzianowski 320lbs/6'1" = 52.6 lbs/foot. I am 265lbs/5'11" = 45 lbs/foot. I think the typical Goliath warrior has a physique more like a professional heavy-lifting athlete than my crisp-devouring self.
Question: Is it reasonable, when creating a Goliath, to use weight way higher than the one provided in the EE Companion, generally going for around 50-53 lbs/foot, so 350-425lbs (or more)?
