The mesh are definatley nice but on some lower to the water boats it is extremely annoying getting splashed from underneath. That is the one reason I went with a white viynal tramp on my 18... besides the $100 difference.
The 16 I raced at youth nationals had some large holes in the black mesh tramp. I have seen several black mesh tramps with the same problem. A dealer told me they were having a problem with the black mesh's durability.. It may have been fixed by now... who knows.
