Ultimate Terrain USA and Mesh

I just purchased UTUSA for FS9 and started downloading some of the 70m mesh here at SimV. The land looks great, but some of the lakes/rivers have large mounds or valleys in the middle of them due to the moved bodies of water from UT. I was just wandering if payware mesh (fsgenesis, fsterrain, etc) lines up better with UT, or if all mesh programs have some problems with bodies of water. Thanks!
