In the grand scheme, it's a concept being discussed. What is said above says that well.
The title of the thread that you suggested is a good one. It puts a face to the hunter and the situation. 35 Whelen/AI need not apply in the scope of that poll. While being a good tool for the job, it's a fringe cartridge, and IMO, it's not reality the poll would be better with that included.
How about a second poll that allows bullet choice as well. Cup and core bullet, (whether long range or otherwise), bonded core, or mono.
Combine results of the chambering, with the bullet style that was chosen. Make that the poster child for the official rokslide first time western elk hunter recommendation.
