OK, Gracie's seat is way too hot this time of year. Looking at airhawk seat cushions and would like to know which model (Airhawk R or Airhawk 2) is the preferred model for a spyder rider. It appears that one is air adjustable and one is not.
Also which size (Lrg. or small for the passenger seat) fits best.

Thank you in advance for your words of wisdom.
