I went with 2-3, and agree with HaverfordWest's assertion that anything sat longer tends to lose relevance anyway in the sea of information available. Besides, if one is desperate to see screen caps of a particular route years after it's launch, there is always Google. It takes very little effort to post something here to the effect of, "Can anyone share some screen shots of Anorak Dave's East Anglia Marsh route. The version is 43E iirc. The last time I saw the pics was eight years ago...etc." Cheers all.
