1) Yes seat is more comfortable than CD70/CG125
2) I have kept Pridor for 3 years (2013-2016) traveled across Punjab and one trip of AJK. If you compare it with CG/Deluxe then you'll find it under-powered (pick wise) when climbing hills specially; other than that its very cool
3) No weight issue I faced
If you'll mostly be driving it in hilly areas with steep climbing then go for Deluxe otherwise Pridor is very comfortable and preferable bike.
