Ive personally used both types of pads Aero and Cant ones, i moved away from Aero as i found them not to my liking regarding the feel and fit. Used the Cant version all of last season and found them to be very comfortable and great protection, i do agree with some comments which say perhaps they could wrap around more and be slightly more fitted.
Still use the Aero for nets etc and I've not had any problems regarding comments made about either brand however id say that's down to me personally being the way i am as my nephew got plenty of stick when playing for Northumberland wearing his Aeros but he got runs so he was ok however he has moved away from them now.
