My Manfrotto MHXPRO-BHQ2 XPRO showed up last week and I snapped a few pictures of it along with my MHXPRO-3W 3 way pan and tilt. The fit and finish on it is pretty impressive, tight tolerances, smooth action, and fairly easy controls. That being said, I won't really know how well it performs until I get out there and try it out.
Load Capacity 22 lb (10 kg)

Weight 1.1 lb (500 g)
I mounted the Pig saddle on it and threw the whole thing onto my Benro carbon tripod. Though it's definitely more compact than the MHXPRO-3W, it sits fairly high above the base of the tripod. I've been reading that some shooters prefer a simple leveling base which is almost a pancake compared to a full ball head. The draw back is less elevation/cant adjustment, so you'll have to decide whether that affects your style of shooting.
I've been looking at the Benro LBA 2 Leveling Base to go with the Benro tripod and decided to order it as well and see which I like better. Some specs for the leveling base:
Load Capacity 110 lb (50 kg)
Top Mount Thread Size 1/4"-20 and 3/8"-16
Tripod Mount Thread Size 3.8"-16 with 1/4"-20 bushing adapter
Adjustment Range +/-15°
Height 1.875" (4.8 cm)
Weight 11.2 oz (318 g)
If the leveling base works out, I'll probably keep the Manfrotto ball head and sell the 3 way pan and tilt.
