I got Steve Simmonds to do the insides of my side screens about 5 years ago. They look nice and cut down draughts and spray coming up through the gap, but make it a bit harder to rest your elbow on the door top.
As a consequence I prefer driving without them in place, a flying jacket solves the draught problem, and visibility is also improved along with the looks. It also makes it much quicker to get the roof up if you're caught in a shower. You don't really need doortops on in the rain unless you've got a long motorway haul to do.
