I have had both fastback is good for very short trips and so now I have the squareback and my wife is happy with it. I also like the looks over the sport tour and its also very comfortable for me.

 

Here's my square back...

 

Thank you both. those picture perspectives really helped.

I'm awaiting some color swatches from C&C right now. but i think the square back will be my choice. the alternativly i may go with the solo and pillion if i decide on a wider passenger area. i'm just not sure i like the look of the sport tour. the square back looks good enough for some shorter day rides
