I have full hood, hood bag, tonneau, full doors, half doors (all CC), half hood, normal shower cap (SBFS), aeroscreen, full windscreen and lightweight full car cover. Some might say I am indecisive but I can run in all sorts of configurations depending on the weather. The tonneau does get used, especially with aero and one half door fitted. Half hood is useful but I find that you do get wet as the rain gets sucked in from behind through the gap. I have an SV so maybe different for the tiddlers! Also depends if you plan to carry SWMBO where I find the tolerances require the full hood and doors to be fitted! Agree that the DRE shift lights will save you some cash.
