I have the regular version (non-X model), weigh 185 lbs, and have had it for about 1.5 years. No problems with stretch-it feels better now than a year ago. I really like it, and have put the X version on my xmas list so I can have one for one of my other bikes. Previous saddle was a Brooks B17 (still have these on other bikes), and what I prefer about the Titanico is it doesn't need to be set up "nose up", like my Brooks.
