Anyone out there with a Sirui T-005 or T-025 tripod who'd like to upgrade the C-10 ball head? I have a very lightly used Feisol CB-30C ball head I'd like to trade. It's in excellent condition, no QR plate, but with box & papers. Unlike the C-10, the Feisol CB-30C has a friction control. Would like to trade for your Sirui C-10 ball head (w/o QR plate). If there's any interest, I'll post close-up pics and we can work out details. :smile: Thanks for your interest!
