Last month, I was debating between purchasing a new carbon fiber tripod (Really Right Stuff TVC-33) or replacing the QR plate head on my Manfrotto aluminum tripod with something that could accept Arca Swiss.
I went a slightly different path. Instead of getting the TVC-33 tripod, I went with the TVC-34L. I decided on the new tripod because I didn't like the center column on my Manfrotto. I tried not to extend the center column to make the tripod more stable but that resulted in me having to lean over to look through the viewfinder. I went with the 34L over the 33 because I can always shorten a tripod but I can't extend one further.
I also picked up three of their spiked feet in preparation for a trip to Virginia Beach.
