Are most of the larger riders, over 275, using stock saddles or have you found the need for upgrades? I am uncomfortable on my current saddle. 100lbs ago the seat worked fine now not so much. I am looking for something that doesn't make me numb after 1/2 hour or to sore to ride without a week long break. I still have the memory of soreness from when I rode 200 miles a week(20 years ago) and just thought "tough it out you wimp." I do not want to tough it out but I also want to avoid a cruiser seat with springs hanging below. Any ideas?
