Pitts your fate will depend very much on your total hours.
As a LTN based pilot you will do BHX and EDI almost exclusively on voyage (the 757 up there rumour has died I'm told). MAN pilots do the ABZ and you might get the odd AGP too (just restarted this winter). You'll do the odd LGW and MAN voyage too.
You won't do runs of 5 or 6 at LTN very often. This is MAN or LGW stuff. And not many night flights, although there are some out of Brum and the odd late LTN schedule to AGP.
I guess 600 hours would be average in recent years for a LTN base cf 800-900 at MAN or LGW.
