There were some issues with Mac users not being able to open the Kentmere guide without encountering some pretty major errors. I have mucked about with it and and updated the layout somewhat and it now seems ok on both Mac and PC. Unfortunately, thanks to some slight glitch in the original file I can't seem to convert it into a standard PDF without incurring some major degradation in the image and diagram quality. Therefore I have had to convert it into a Hi-Res PDF, thus it is now 25mb, rather than the original 8.5mb. On the upside it does look quite crisp once you have eventually downloaded it.
