i'm looking at purchasing a new tripod head. i currently have a bogen 488 ball head on my gitzo 1340. the 488 ball head is not even rated to hold 4x5. i use a toyo 4x5. i'm not sure whether i should get a ball head or a pan. i love the feel and quickness of a ball head and plus that's what i'm used to. i shoot 35mm as well, so i wouldn't have to switch heads if i got a ball head. the two heads i am looking at are the bogen 329RC4 tilt/pan head and the bogen 490 ballhead, both with quick release, and both support 4x5. plus, is the bogen hex quick release system better? any opinions? thanks!
