I do similar pretty much everyday. Hey ho.
The location of my law breaking is at the top of a road which has 3 lanes and traffic lights. RH lane is for turning right and has its own filter light. 2 LH lanes are for turning left. Round the corner to the left the road opens up to 3 lanes (4 slightly further down the road) where the 2 left hand lanes are for going straight on, while the outer one(s) are for bearing right down a separate road (which I need to do).
So, primary position in middle lane at the first set of lights... to then go left round the corner and take primary in the third lane to bear right until it opens to four lanes and cars can get past safely... down to the next set of lights about 50m away.
The first road is usually chocker in the morning so there's generally no "slotting in" option... but I will do so if there's an opportunity. I usually go past all the traffic and slowly cross the solid white line whilst leaving space for peds to cross the road behind me. This puts me about 3 - 5m ahead of the cars but in clear view and where I can see the lights easily (on opposite side of road). It is also far enough from the main carriageway which runs across the top to be nowhere near interfering with the traffic there.
It's safer for me, lets peds cross, and allows me to set off without holding cars up (it's a little rise immediately after the lights which I hit after I've clipped in and got going).
I am so naughty!
