Each pre-season I pick one download tactic to try for that season and make a tactic of my own (plus a variation of that with sliders set to whatever positions aren't covered by the main two that I feel might be most useful). Last season I used Raikan's Ama-Zing tactic alongside a 4123 of my own. Both got used throughout the season, although by the end of it I was playing most games with Raikan's as it was better than my own in most circumstances (certainly by the time I got through customising it for my players). I'm about to start season 5 and am planning an asymetric 41212 and have yet to pic a download.
For me the benefits of this are that by getting to see how other people's tactics work, I'm always improving my understanding of how to put my own ideas into practice.
