I have had both the Dark Archer and a "few" Bear Takedowns. They are completely different animals. I shot the Dark Archer quite well and probably shouldn't have sold it!
The Bear Takedowns over the years have had very different grips and different feel to them. To me the Grips on the 80's - early 90's Green Stripers feel best, but there are guys out there that feel they are too thin. I had a 2011 and the grip was terrible to me. The guy I sold it too really likes it, so it is all in personal preference.
You also need to ask your self how much do you want to spend as the prices will vary greatly depending on what year/style you want.
If I knew I could get another "Red Striper" in a grip I liked I would buy one in a heartbeat. That being said I won't buy another one unless I can put my hands on it first.
Just to throw in another speed bump, there is also the question of whether you want an A Handle or a B Handle!!
