yes the seem is dead center down the back and there is a realy wide mesh segment at eather end which if you put a flat texture on it will cause the compression you see. the ideal thing is to stretch out the texture evenly in those areas I haven't found an easy way of doing that except for with squizz an expensive photoshop plugin ($140.00 just for a plug-in!!) theres also a cheeper program called pm Rubber but I tried the demo and was less then enthused.
