RE: prop style for Saito .82 FS
APC uses all sorts of descriptive terms but they only have one offering in most of the sizes (exclude pusher and 'electric only' versions of some sizes). I know they have some models that are available with "wide" or "narrow" blades in addition to the standard blade.
The 14x6 (part number LP14060) is listed as a "sport prop" now but I have several at home that carry the "Pattern" description (same part number).
