Add on drying the thing / weight (dependent on material) and storage when cycling. The lighter efforts as posted by the OP and Polycro etc never lasted the length of a tour,they always ripped - the heavier stuff was just that - too much weight if your'e attempting to keep weight down. That said I'll probably regret it but I carry a repair kit and if I can (weather and light permitting) absolutely scrutinise my pitch before chucking the tent up.
well not the one I suggest - it wont rip very easy at all is a nice middle way between weight and thickness
