When I weighed my saddle, it weighed in at 354g.
The Swallow seems to be a little flatter across the back than the Team Pro that I tried. (bmike would be able to tell you for sure about that). I've not tried the Swift, so I can't tell you about that.
For me, the flatness across the top makes it feel wider, and my sit bones are not "falling off the edge" when I sit up. However, the saddle was intended to be ridden in the more agressive aero position. It is quite comfortable in that position.
The rails on the Swallow are longer, which I really like! It gives more fore/aft adjustability - especially aft.
The ti frame seems to be a little flexi and absorbs shock (but not so much that you compormise power transfer).
The Swallow is flatter across the top than my Team Pro. It has a subtle, yet different shape than most of the Brooks I've seen. Definitely for a more aggressive posture. My sit bones feel properly positioned on the Swallow or the Pro, but I too felt like I was rolling off the Pro when in the drops. (Now that I have aerobars, I'm glad I have the narrow and long Swallow) The Swallow is hard. I do feel it, but in the back side of my back side - my sit bone area was a little sore at the start... but this seems to come and go. Not anything I'm going to worry about, as I know, from my experience with the Team Pro, that this will pass.
I've noticed a tiny bit of flex in the Ti frame as well, and my seatpost is a bit flexy. All this is fine with me, as I have the bike set up for long rides, and comfort is key. If I were hammering hard, short rides I'd swap my seatpost.
My Swallow continues to be comfy. Firm on the sit bones, I've been out for 3+ hours and haven't encountered the male numbness and hot seat I had with the Selle. I've been riding the aerobars quite a bit on the trainer, and I'm still tweaking the tilt on the saddle. Trying to find the sweet spot for hoods and aero position. Scheduling a session next month with a sports physiologist(sp?) who does biomechanical bike fitting. Should be fun, and helpful.
