The flourishes on Dangerous aren't all that hard, provided that you know your stuff beforehand such as the Sybil, One Hand Revolution, etc. Some of the stuff will take practice but the majority of the material is attainable for the intermediate flourisher. In comparison to the Trilogy, I would say that Dangerous is a lot easier but the Trilogy has better flourishes. If you want something easier, go with Dangerous and then work your way up to Dan and Dave's material.
