PMASHA, my May roster has me performing like an airbourne yoyo between East and West. Is this what you mean by a "constructed roster". The theory of pinging backwards and forwards on a bit of elastic pinned to the Bouncy Castle somehow keeps my body clock glued to DXB time? If so please please try it, it doesnt work, it actually destroys any chance of a rest pattern rhthym and actively fatigues as if designed to do so. Brilliant!
