He's spot on about the grass.
RMM also made some nice cat tails and JVC has some nice grass that looks like cat tails so I you are looking for reeds, avoid the assets Reeds 1, Reeds 2, and Reeds 3.
They are really high-polygon and will melt your PC if you use them in the quantities needed to represent the edges of a swamp. This was a problem with them even when they came out nearly 15 years ago.
