I have a Triumph King/Queen on my scrambler and find it very comfortable. It does sit higher than a stock seat - so longer legged riders may appreciate it more, shorter riders not so much. It looks OK on the bike but not exactly scrambler-esque for overall style.
I had a corbin gunfighter & lady on my Triumph Sprint and was very DISAPPOINTED. Only corbin I ever had and I can't figure why everyone praises them so much. Corbin did sit you down lower on bike but seat was very hard and actually less comfortable monkey-butt wise than the stock seat. Corbin was also much, much heavier so overall bike weight actually increased. I also found corbin customer service UNHELPFUL - my seat had a "latching" issue, corbin seat stud was significantly shorter than stock seat latch, corbin was unresponsive to the issue - I ended up fabricating a new stud myself.
