I've posted this cus I wanted to make one or two points and observations, mostly on things many of you have discussed here before.
My Route; M40/A40 to Oxford, then A44 through the Cotswolds to Worcester and A443 to Tenbury Wells and finally the A49 to Ludlow. (were now only 40 miles from Rhayader)
For the first 50 mile stretch on the motorway I put to good use advice I'd read here, namely 'making that lane your own' and 'avoid becoming gutter trash', it worked perfectly
I had no problems at all, I was pleased to see how much respect I was given, particularly by lorry drivers who I tailgated at every opportunity. 
Next the Cotswold stretch, the A44 was a joy to ride, beautiful towns and villages like Chipping Norton and Morton-In-Marsh, the road was quiet and I could have easily spent a week on this stretch alone. I did notice however car drivers will give you much less room, the 'lanes' on the motorway were more closely observed!
Finally the last drag over the twisty roads to Tenbury and Ludlow where the scent in the air was of the apple orchards and bugs splatting on my visor were as big as ripe plums!
I managed 60-65 mph easily on the motorway and more at a push
also 4.2 litres to cover 155 miles = 168 miles to the gallon. 
Yes......... it was my Innova ...... sorry to disappoint!
Ludlow Castle and the town beyond.
Day trip to Much Wenlock.
And some believe the site of the first modern Olympics!
Loved it.
Every few miles (on the Wenlock Rd) there's yellow and black motorbike signs stating 'RIDE CAREFULLY' and 'BIKES BEWARE'.
