I am new to the forum and to cycling. I love both! I am in the market for a Brooks saddle to put on my Gary Fisher Nirvana. I originally thought about the B17, but Wallingford Bike shop says that I might ought to look at the B68. Do any of you have experience with these saddles? Any other suggestions for a clydesdale saddle? I am 5' 11" and weigh 255 (I just have recently lost 110 pounds and really what to use cycling to get into better shape). I ride about 60 miles per week right now with hopes to soon up that. Thanks in advance for the help!
