HP A-series, H3C, Huawei and their capabilities in real-life

Hi list Does anyone have (or know somebody who has) real-life experience of HP A-series (former Huawei and H3C) high-end routers in service provider environment? From the specs they look very good (both features and performance) but the specs don't tell everything and nothing can replace real-life experience. The features I'm interested in include (not in any specific order) - v4 and v6 routing - BGP (full feed) - OSPF and IS-IS - MPLS(-TE) P/PE functionality (RSVP, L3VPN, VPLS) For example this box http://h17007.www1.hp.com/us/en/products/routers/HP_A8800_Router_Series/inde... Any info or pointers greatly appreciated. Rgds, Mark
