OK, I'll be the discenting opinion again as usual

I will advise that the Brooks may be for you, but it is also fairly likely that it won't be. I know that I found the one I had to be nothing special. I found it just OK out of the box and liked it less and less as it broke in. By the time it had deep dimples I hated it and took it off.

I have found that the saddles that came with my bikes were all fine once I got my butt broken in to suit them and I would use any of them for another coast to coast trip without hesitation. I always advise putting in at least several hundred miles on the saddle that you have on your bike and giving it a good chance before swapping.

The Brooks saddles are all quite heavy and the ones with springs especially so. It may be worth it to some, but it definitely was not for me.

I think that much of your weight should be carried by your legs and your legs should act as the springs. That is best acomplished by having your bars fairly low and having your core muscles fairly strong. A sit up and beg posture will not suffice if you want to minimize the weight on the saddle. You should also have elbows bent and a relaxed upper body with finger draped loosely over the bars. If having your bars lower than the saddle is a problem for you, I'd advise having you bars as low as is comfortable for you and easing into lower yet as you log some miles and adjust to the posture. I found the sweet spot for me is about 4" below the saddle, but that will vary rider to rider.

I have found that wide and/or highly padded saddles are to be avoided and racing saddles are surprisingly comfortable <b>once you adjust to them</b>.

All just one man's opinion, but it is based on a fair number of longish to long tours and a lot of local riding over many years.
