Thanks for the input guys.
I did have another thread when I was synced at about 43.2Mbps and SNRM was 6.9dB then, so I might try 42/42.5 first, and see how that goes.
As I say, I'll revisit this in a month, as I'll probably give my line some time with DLM at first before messing around with it.
My latest errors are in the first post at the top of this thread, and my first initial post with stats is here
