I have been working around the limitations of my RRS BH-55 for a number of years now.
Ball heads are great for landscapes and portraiture, but even the very high end ball heads will droop just a touch. I had been looking at getting a geared head for a number of years for this specialty work, but unfortunately the only two options were the Arca-Swiss line (think $$$$ very high end and expensive) and the Manfrotto line with its proprietary plate design (yes, there are Arca-Swiss to Manfrotto conversion kits available).
I recently discovered Benro has launched a geared head that was quite affordable (I got mine for $CAD 250 on Amazon), which is quite light weight and uses Arca-Swiss plates natively.
I've just started running it through its paces and am impressed so far. Very light weight, reasonable capacity (6kg / 13 lb).
It has a coarse adjustment on all three axes ans well as the fine adjustments one expects from one of these heads.
