I have found quite a lot of success using the pratt truss (because the way I think of it, since the longer beams are in tension rather than compression, you don't need them as big/dense, so you can save a little weight using them) but I would say just use what has worked for you in the past. I have learned the hard way the consequences of changing your design just before a big tournament.AnonymousMouseRI wrote:How has the pratt truss worked out? We tried it at states (even though we got it together in about a day), and it only held 17 lbs. We have to finagle a new design for nationals. Any ideas? I am sort of at a loss.
