Vladimir – like you I have a 4-seater. The original hood was Everflex, but I have had that replaced with Mohair and a hood cover. A characteristic of the 4-seater hoods (compared with those of the 2-seaters) is the seemingly acres of material that has to be manipulated, particularly when taking the hood down – top two folds out, bottom fold inboard, then making a “hospital bed corner” of the sides, before tucking into the hood cover and battening down. As it happens I can do this fairly quickly, but are you sure you want to add to this palaver with an extra layer of material?
You may not want to hear this but I have chosen the opposite way – hood down and no side screens (and I use the car all year round) . Strangely I have found this less noisy and less draughty; with the imperfect road surfaces we have to endure I got fed up with constantly clattering four side-screens. And with side-screens on there was a piercing draught in the passenger foot-well; take them off and it’s gone.
So with the correct clothes and headgear - and admittedly ear defenders for dual-carriageway and motorway driving (sometimes it can’t be avoided) – I find it quieter to drive in this configuration.
