Got my Corbin seat today...have only ridden 15 miles on it, but it's a vast improvement over the stock seat.
The seat is wider, with more coverage across the butt area, plus is harder (without being too hard), giving more support. My prior motorcycle ha a seat that was too soft, giving terrible butt problems after 3 hours...immediately cured with a Corbin, that was stiffer.
I got the non-heated version, with basic black covering. I'm planning a long trip Sat and Sun so will post more after I've spent 20 hours in the saddle.
BTW...I'm putting my Airhawk up for sale if anyone wants it....Cruiser Large size for fit on the ST.
