I have both a straight and a "micro-adjust" seat post, so either type saddle will work fine for me. I'm also thinking that to try the style without spending the $$, there are lots of "Brooks imitations" on eBay for ⅓ or less the cost of a Brooks. I wouldn't expect them to be as durable, but I could at least try the design to determine whether or not it worked for me. If I specifically liked one or another, then I could resell the imitation and buy a Brooks. Jumping straight into a Brooks without having tried the "architecture" of the saddle is an expensive experiment...
A typical replica for $27.89:
Another for $42.99
