Thread: Flip-up scope caps vs Neoprene scope covers

Pretty simple question, what's your preference and why relating to flip up scope caps vs neoprene scope covers? I can see the pros and cons to both but would like others' input as I haven't really used either (though wish I had something to keep the lenses clean more than a few times!)

Edit - bikini style is also an option, really I'd just like to not have dirt/water/snow on my lenses.
