Would rather take the A41 - M1 - M6 - M74 - M8 - A71 - Western Approach - A70 - B700 - A7.
A2 Derry/London/Derry - Newry
Easier to take the A6 - M2 - A12 - M1 - A1
You can't access the M8 eastbound from the M74. You'd need to include the M73.
Yes I was hoping noone would notice

, unless I did a U turn at J23 and included the B768, so it would be M73 or A725, then onto the A8, then M8 towards Edinburgh.
My point was that the M6 corridor seems to be a better route than following the A1 all the way.

In a similar vein, a few of the NI Trunk routes (even if you adjust the routing to go on motorways) go long way round: T3 - you wouldn't go via Omagh to get to Derry from Belfast. Ditto T7 and going via Coleraine (OK, the Glenshane Pass was only trunked more recently and wasn't very good quailty and that would have roughly followed the planned motorway route). Also T8 from Moira round over half of Lough Neagh. T15 from Warrenpoint to Coleraine via Cookstown is a sensible route, but the motorways and better quality roads make via Belfast the preferable route.
In an even more similar vein to the A2 - N56, N59, N70, N71, etc that follow the coast - though you do get people doing it as tourist routes.
I couldn't even tell you where the Trunk routes are! (Ashamed to call myself a Sabre-er). I do know the E1 travels from Larne though.
Generally the road numbers here for major roads are usually the ones you would take.
A2 being an exception that follows the coast, it has a few tourist routes along the North and Ards coasts.
