I switched to Arca-Swiss QR system from the Manfrotto RC2 about 17 years ago and have never looked back. The A-S system is far more precise and secure, even if it is slightly less convenient to fit and load. The problem with the Manfrottol RC2 is that the plates have a small amount of play in the clamps that make precise positioning difficult ... Enough so to really annoy at some point ... Where nothing like that exists in an A-S clamp and plate system.
I have a very nice Acratech Ultimate Ball Head that I'm no longer using (I moved to Arca-Swiss P0 and P0 Hybrid a few years back). It's in primo condition and I'd be happy to sell it at a fair price. It's been fitted with a RRS lever action clamp. I also have both Markins Q3 Emilie and an Acratech GP heads with A-S clamps for sale, they have the knob type clamp though. All excellent quality.
