I have several suits at my disposal. Tailor made BKS, mega heavy, but definately the best thing to crash in. I dont do track stuff, but would consider myself to be a fast 'touring' road rider. The BKS hasn't been on me for over a year. I currently only ride in a two piece fabric suit. Either HG bib and brace with HG jacket. or, change the jacket for a Fabric Dainese one.
all my fabric stuff is Goretex, to guarantee waterproof-ness and breathability. If anybody asks my recommendation, If you plan to crash... then all leather... If you tour and hope not to crash, leather trousers and a good quality, armoured Goretex jacket. But I do all fabric Goretex stuff and so far have been ok as far as luck goes!
