Printer and paper feed

Ok, now using a Canon MX870 which has a rear paper feed, as well as a bottom tray feed. Looking at a Canon MG7520 (on sale at Best Buy), It has two trays, one for photo paper and one for plain paper, both on the bottom and no rear paper feed. Does anyone have any experience or thoughts about feeding card stock, 110lb from a bottom tray and rolled around 180 degrees for printing????

Thank you for your time
