When my 115 arrived, I could hardly get it out of the case, the foam was so tight. Since I like a little extra room and don't like to rub the scope raw, I immediately took out the carving knife and created space around the dewshield and focuser. I will never carry a diagonal or eyepieces in the case - I have a separate case for those items.
I use a Lenscoat "Hoodie" to cover the front end of my scopes. It doesn't ever scratch anything, but it creates a slightly "fatter" dewshield diameter. And I don't like anything pushing on the focus knobs. They are fragile enough without making things worse by forcing them into a tight spot.
If I ever have to sell my scope, I'll wrap it with bubble wrap to keep it tight for shipping.
Cheers,
Ron
