Well, I just bit the bullet on a new set of carbon legs and now need to figure out my head situation. I've only used pan-heads in the past and after searching this forum a few times for a good solid answer, I still don't know if a ball head is right for me.
I will be using a Mamiya 7 II with lenses from 43mm to 210mm and the occasional 35mm rangefinder. I go hiking/backpacking lots and hence the need for a lightweight tripod and head.
Have people had lots of problems with sand in their ball heads? It's awfully dusty and sandy down here.
