@Tree_Climber , Hi Kathy -- I don't have any experience with that brand, or any brand other than the Rion that I have; but the Grandio Elite looks exactly like mine, other than the Grandio frame is metal and mine has a "resin" frame (which I would not recommend). However, I can say that the barn-roof style has done very well for me in terms of winter snow load.
How do you want to utilize your GH? Do you plan to heat it in the winter? what size are you thinking of getting?
