Before I had seen a 4.5" barreled version I figured the 5.5" was good, but the 3.5" barrel Taylor's sells as interesting. Now that there's a 4.5" barrel I'd likely just get that model and be done, though I still like the idea of swapping barrels.
I also like the idea of a rounded grip, though I'm not sure I'd really want a full on birdshead grip, but maybe something more like what I've seen done on Remingtons where the rear portion is more rounded. But I do like the birdshead too.
