I very rarely imaged with the 60 double stacked - although the contrast improved the exp had to increase and frame rates reduced so I just stuck to the single (this is why I went for the single 80 - I can add the double later without factory matching if need be).
Please note that I have had one imaging session with the 80 under awful conditions but I feel the 80 will be awesome - I would go for the 80!
Here is my site with images - it may help?
2008/09 all with SM40
2010 from March are Lunt60
2011 are all Lunt60
