I realize where your coming from and the set would be better then just the sizing die even though you can use a standard 35Whelen seating die to load 35 Whelen /AI ammo. I would get the hunter set with the micrometer seating die since I added the micrometer later when I discovered inconsistency when using a standard seating die and the big .358 bullets tolerances aren't as tight as say a .308, 6.5, 7mm or other bullet designed for long range shooting so each bullet seated needs to be adjusted to be seated to the same OAL. And the Accubonds are one of the bullets I load and shoot in mine.
I also use the Hornady comparator to check OAL with each bullet I seat to get the same OAL for all calibers I load.
