I swear by the Swallow. I have four, on different bikes (well, yeah).
Also, a good representation of a broken-in Swallow's comfort: I rode the Aids Lifecycle 9 event, from San Francisco to Los Angeles, on a Swallow. This was on a fixed-gear bike. If you've ridden fixed, you know it's less forgiving on the seat, as you never rest and are moving around here and there over long hauls to alleviate the aggravation from tat extra friction. I rode nearly 600 miles in that week, on that Swallow. I don't know what people commented on more: the fixed-gear, or the saddle!
