Not a gun writer, but have made multiple trips to Africa, plus trips to South America and travel with guns domestically (USA).
I find the Pelican case to be excessively heavy. Some airlines do have a limit as to how much a rifle case can weigh. My usual armament when traveling to Africa consists of a .416 Rigby magazine rifle and a .470 nitro express. The two weigh 22 lbs combined. Add that to the weight of the case and you've got about 50 lbs total.
In 2012, on a trip to Namibia, I used a brand new Americase "Safari" two gun case. It arrived in Joberg badly damaged, but the rifles inside were undamaged. To their credit, Americase replaced it free of charge upon my return. I have not used the replacement case and intend to sell it.
My preferred cases are made by Impact. They are reasonably lightweight and over the course of multiple safaris, I have never experienced either damage to the case or damage to my rifles. Impact, based on personal experience, is my preferred case.
