We just bought a 3630 which has a world called Genera-7-2-2.load, which apparently includes the ECO#2 patches in the world. Aside from gaining FEP blocks (33500 for 7.2 and 12000 for the added incremental of ECO#2), is it worth transfering this world to our 3600 and re-building worlds? Is 7.2.2 better? Best, PANgaro
