Best driving route from Glasgow to Leeds

[Mr Overheads]

I'll be joining the AMV8 club week on Friday all being well when I collect an N400 from a private buyer in Glasgow, but I live in Leeds. so....

It's the perfect opportunity to give the car a good run back from Glasgow and as my parents live in Darlington I can pop in there for a break in the long drive.

So there are several main options for the route from Glasgow to Darlington:

1) M/A74 > M5 Carlisle > M6 Penrith > A66 to Darlington - A66 being the most interesting part of the drive (174 miles, 3hours)
