Limulus,
Daunting isn't it mate . Good choices for all of the above replies. Your choice is obviously to cover all eventualities because your mind is racing with scenario's that could need 6x to 24x mags. There is an element of luxury in the Zeiss you mentioned, there is also a compromise ther too....it's bulk ! With 2200 quid to spend the choice is staggering, my guess is that you've probably changed your mind a hundred times but keep coming back to an 'all eventualities' scope. Realistically you will seldom need more than 12x mag for the longest shots, and even then that would take a rock steady hold to prevent it shaking all over your target area. Just wielding that monster around could cause problems in itself, the turrets are tall and can foul on the most insignificant objects. The realities are that you will seldom have time to fiddle about with ballistic turrets, so rely on a well set zero that covers your most often encountered ranges. If you are lamping foxes and woodland stalking with the same rifle then select a reticle that has thick posts leading to a thin / finer crosshair such as a no. 4. Illuminated reticles are a personal choice, they don't have to be turned on all the time so getting one increases your choices, so with that budget go for one anyway. To be sure of quality and service backup stick to the German scopes, there are other very good quality brands out ther but i'm guessing you want peace of mind so don't purchase something else and then always wonder "what if" ! Go for a larger objective lens, 50mm to 56mm work very well because they increase the light transmission to your eye in darker conditions, bear in mind that maximum light transmission (a factor of 7 is all your eye can detect) is easily calculated by dividing that objective diameter by the magnification in use eg 50 mm divided by 7x mag gives a factor of 7 = maximum light to the eye. A 56mm would be 8x mag. Lower magnificayion capability gives you a wider field of view through the scope, so making target aquisition easier in difficult conditions. A very good all round no nonsense scope is 7x50 and 8x56, I've used a Schmidt Bender 8x56 for years on foxes and deer and never wished for it to do anything more than what it does, and does very well...see it and hit it !Looking at all the facts go for a 2.5 -3 (lower end mag) with a 12 to 15 (upper end mag) and 50mm or 56mm objective lens. Familiarise yourself as often as possible with your rifle and calibre characteristics, find out the best set zero distance and then you can just concentrate on hitting what you are looking at, instead of worrying about details that won't affect the outcome, if you shoot straight.
Don't worry, Be Happy
Cheers
