Splice really dont seem that much better in my opinion. From the outside the lens looks a lot bigger, but there is a lot of plastic on the inside which takes away some of the extra lens.
So you can see a little bit better out of the splices, but it isnt that great.
I was definitely expecting more peripheral out of the splices... still prefer them though... could just be cause i fall head over heals for whatever the hell the latest is oakley pumps out
