The elite Open players are 25-30 shots better than me on such courses under such set-ups, but that hole would be one of the easiest 4s I could ever make...with a chance for 3 and when the pin in the front a possible 2.
The back pin? i'd be playing a 175-185 shot wide to the front right edge, and trying to up and down for better than "4"
I don't care what the yardage is or what the shape or architectural demands are or what the rightful traditional "par" may be, every hole is a par 4 for me...easy, average, difficult, impossible, whatever.
17 PB is therefore an exhilarating opportunity hole in my evaluation, a brilliant bit of fun that makes a very do-able 4 with a solid chance for something better.
cheers
