I glanced through the thread before posting, so here's my $0.02:
First, you might want to wait until the V-Aviar comes out rather than the Whale. The Whale is based on the Big Bead Aviar Driver mold, while the V-Aviar is based on the Aviar P&A mold (that is the Nova and McPro Aviar, etc. base).
Second, I'd suggest you look at the Pure (3,3,0,0). The Opto Pure is flat, it flies straight, it goes far (it's almost midrange length out of a putter). You could try Zero Hard (my favorite), or Zero Medium as a putting putter.
I also would recommend looking at the Judge (2,4,0, 0.5)(really should be 3,4,0,1) or Warden (2,4,0,0.5). The Judge is beaded, the Warden is not. They're both flat, fairly shallow. I use a Lucid Judge for throwing shots I want to put a touch of anny on, and the Classic Warden (equivalent of the Zero Hard plastic) is my in-the-circle putter.
You've ruled out my other suggestions, so I'll leave it to the above for now...
