i am so proud that an idea i did last year finaly reached wakeboard mag. I did the same thing on budget and all my friends laughed at me. now we see whos laughing 
. this was before i went to the upgrade budget version. posted it some where but don't remeber where or when.
scott j. gave me this idea.
other method is to go to used tire stores and buy the used lead weights, get some 6 in pvc pour it in there cut the sections of course to fit the space your using, fill in air space with sand and then cap off the ends. smaller than the cement and easier to move.
