Is there any reason that I might need more than one tripod? I have a "nice" tripod setup, and I have another that I'm not sure if I could keep or sell. I have a tendency to accumulate gear just out of an unwillingness to let stuff go, thinking I might need them, then as soon as I give up and sell something, I need it. I currently have this setup: Bogen/Manfrotto 3021N legs http://www.adorama.com/BG3021N.html Manfrotto Grip action ball head http://www.adorama.com/BG322RC2.html I also have this tripod just sitting around. Its not a bad piece, its just not being used at the moment. http://www.adorama.com/BG728B.html Thoughts?
