I'd say to stick with cheaper saddles until you have some idea what shape/style/size works for you, and only then get something lighter (if you feel the need). Unless you're lucky, it could take a few attempts to find the right saddle shape.
For example, I found the saddle on my Trek bike to be uncomfortable initially, so got a cheap-ish gel saddle from Amazon. That was better to start with, but I found the gel to actually cause chafing after an hour or two on the bike. I bought a Madison Flux (same as the Charge Spoon) as so many recommended it, but found the lack of a centre cutout to be a major problem. That saddle, however, made it clear to me that that type of shape and more curved surface was the way to go (my Trek saddle had a fairly flat surface and a different shape). I finally got a good deal on a Fizik Aliante, which I'm pretty happy with for now.
