As mentioned, the preference is unsubstantiated performance wise, but it's a preference I think we both have regardless.
That is a pretty bold claim, but lucky you, I have nothing to back my claim either lol. I do like that the AR Design is a very smooth and long taper to 2.25", as opposed to the abrupt steps of other DPs, but that 2.25" section just went from a small easily corrected section, to a foot long section that cannot be cost effectively corrected. It is a beautiful design though, just not my cup of tea.
