I have a Manfrotto 725b digi which I quite like. However, the tripod head isn't strong enough for my current equipment. I use the tripod primarily for my hasselblad and (don't kill me) Canon 5D w/ grip and some longer lenses. The head obviously isn't built for such a heavy camera, and it slips which is annoying. What I want is a tripod with a head strong enough for these cameras, but doesn't weigh a ton! I'd also like a built in level (something with the manfrotto lacks). Any recommendations?
