I'm trying to decide on a field tripod for 8x10 and can't make up my mind. I've decided on the Gitzo 1570M head but can't choose between the wooden Ries J 100-2 , the Gitzo CF 1548, or the aluminium Gitzo 1410 or 1500. The tripod will be use d in sand, rocks and forests. I like the Ries but can't be sure that it is large enough for my Deardorff. Help!
