My memory is that the PSS was worse but I don't think I did any long rides on it, and too much time has passed for me to remember what the PSS2 was like. It's unlikely to be as bad as the SDG Ti Fly I have on all my modern bikes! Two 50km+ days on that definitely leave you feeling broken. Wasn't the PSS2 an attempt to copy the original WTB SST 2k with the droop nose?I remember my PSS2 being the most uncomfortable thing I've ever sat on. Looked pretty good though.
