RRS informed me that my 5D L-bracket order will be shipped around 11/1.
They are great folks to deal with.
BTW - they are taking phone orders now for their new BH-40 mid-sized ball head. About $325 with lever clamp. Shipment start in 2 weeks. Sounds like a nice match for a 12-series Gitzo rig.
Really Right Stuff have been inundated with orders, and in 2 days of ordering have filled their first shipment. I just ordered a BH-40 and dispach is now at approx 4-6 weeks.
