I love Terry Saddles, but as I and sure you will hear a lot, fit is key. Terry's fit me great. Go look at seats and sit on them. You may have to try more then one to get the right fit.

As for weight, I have to qualify it is first by saying I don't really care. I figure I sweat more water weight in the first 15 minutes of a ride then I could lose but running no seat. I ride a 35 lbs bike, and it goes great. My brother has done everything he can to keep his bike light, and it is. Last time we weighted it, 22 lbs for a large FS. Very Very Very light. But when we go for a ride, you would think my bike was the light one. I drop him at will on the up hills. Last time we road, I averaged 6 mph faster. In spite of the 28% weight penalty.
