Matt, I wouldn't dare to argue with you but you know, most of the blanks that a company like Harrisons use are all made on the mandrels peculiar to Harrisons and no one else, different mandrels for different test curves. Somewhere in Harrisons range will be a top section the same as yours, soft and forgiving, I wouldn't have thought Harrisons would order a mandrel specifically for Peregrine.
Remember even Harrisons now import their blanks they aren't producing their own any longer and that being so then a company should be able buy the blanks direct from the manufacturer, there isn't that many of them these days. If they want blanks with a specific action or strengths peculiar to Harrisons rods then I can understand the manufacturer not supplying them to another competing company so Peregrine could only obtain those blanks that Harrisons use from Harrisons, do you see what I mean.
