There is a lot to learn about Parkers but be advised to not just jump in and grab the first one that presents itself. You'll need to consider the fit, the weight, the appropriate gauge for your shooting needs... You know all of this stuff - you've been around doubles for a while. If you choose carefully you won't be disappointed.

You're quite right, and I had no intention of jumping in in a hurry. I have a voice in the back of my head telling me I need another shotgun like I need another hole in my head, and another voice telling me I need to be open to having experiences.... I've decided to compromise and look and shop around and be open to something popping up and to govern my buying by requiring a certain dollar level in the bank account before saying "yes". I was hoping for some of the harder technical details I need to look for - or being pointed at references where I can study - so I can be an intelligent buyer.
All that said, I've tried for years to live in that "be open for experiences" mode and it has had some excellent results. I once got a prewar Payne bamboo rod - needed some work, but nothing out of the ordinary - for $300 when I bumbled into it at a fly shop and just happened to have my checkbook in the car. Post the work, it's worth 6-7 times that. But I like to fish it and it's a good rod to fish.
(I say "a" because one Parker is rarely enough if you do several kinds of shooting and hunting).
I was afraid of that.
