I've got the Gray Nicolls Supernova, it's a fantastic bag and has plenty of space for kit. In my bag I carry 3 bats, 3 pairs of gloves, Aero P1 thigh pads, helmet, batting pads all internally/in the bat compartment. Externally I carry 3 pairs of Oakley sunglasses, bat repair and maintenance equipment, medical supplies such as freeze sprays, gels etc. I also carry other random accessories such as sweatbands, glasses cleaning kit and cold clothing eg club beanie. I could fit two pairs of boots in the duffle but I only keep one pair in the duffle itself as I put my match pair in my sorts bag so they don't get squashed as much.
I would highly recommend the Supernova as it carries plenty of kit and allows you to set it up how you like it rather than other ruffles only really working one way
