Re BRAS profiling, the new system on WBC, which is what you would be on if not LLU, is a lot better than the old one. IP Profile is 88.2% of connection speed, (which in effect absorbs a lot of the overheads), and it adjust immediately to the connection speed. In the case of a few ISPs, Plusnet being one, the ISP holds a copy of the BT IP Profile but rounded down, and applies that. The "copying" procedure fails sometimes and may need to be triggered by support.
The system also now has a 3dB noise margin setting which it can apply on stable lines. That can add over 1Mbps to the connection speed on ADSL2+ compared to the standard 6dB.
Sky LLU I believe uses a standard setting of 7dB.
TT LLU I'm not sure about. There are several resellers using TT exchange equipment with their own backhaul not TT's. Vivaciti is one.
In my opinion the benefits of speed and lack of IP Profiling that LLU used to have are now largely gone. However they are still very cheap compared to WBC-based and TT resellers. (O2/Be are a different case again, but not available to you).
