I ended up buying the Titan and love it!! Only bad thing is I can't use the seat or padding this year due to the odor in the cloth. I called Summit and they said I could wash it in a bathtub so I did and it helped somewhat. I've got the seat and padding hanging outdoors.
I purchase a web type seat made by Hazmore and its sweet and gets the job done and has no odor but not near as comfy as the Summit seat.
