I think that anxiety arising from riding in the rain is partially self inflicted but not entirely. I have been riding two wheels for 60+ years and only recently Spyders. Last fall I was trapped in a ride that I had to complete in relatively heavy rain while riding my RTL. I was surprised how well it went. I think that was more due to experience than the Spyder. I agree with Slice's comments that the faster you go the better the riding circumstances are(within reason of course). Also, when the rain starts to affect vision, I just stand up and let the wind clear my face shield. I do not ride with my windshield at it's highest but just high enough that the spray off of the windshield is deflected over the top of my helmet.
