Rhumba's mesh from 2009 works well in the PTO. It's his watermasks from the same year which are the problem. The more accurate coastlines inundate many seaside aerodromes and towns. I don't use these files in the PTO.
Instead I use Rhumba's Pacific coastal flattens and water files dated 2002 in my PTO. They work well in general. If you have Maskrider's and UncleTgt's scenery installed, the following Rhumba 2002 coastal flattens need to be deleted:
