Help please. Devon to Chester via decent roads through Wales

[VTECMatt]

I have a meeting in Chester next Thursday at 11am, in typical pistonhead fashion i want to make use of the opportunity, I am going to wheel out my Elise for the trip, leave at 3am from just outside of Newton Abbot Devon. I don't know Wales at all so any advice would be greatly appreciated on decent roads, I am thinking a 2 hour detour is all I can manage.

TIA

Matt
