"The dilema is a lifelong desire for a Parker."
That is a very telling statement. The RBL is unlikely to satisfy a life long desire. It is therefore most likely going to come up short in your mind. You will be reminded of that when you finally see a nice Parker for sale (always seems to happen right after buying a new gun) and especially if you are in the company of a nice Parker in the hands of a hunting partner.
I would rather have the Parker, even if that meant having to compromise on the BTFE or straight grip.
Remember life is short, I would fulfill my desire.
