I've tried maple leaf to no succes, buterfly worked better, but very mixed results. The wide diamond from Marco is sth I haven't thought of yet. Probably because I'll have to bench my best player, but I might have a try out nevertheless.
Tell us the results if you've tried it out please. I'm wondering if it works with other teams aswell... ;-)
However, good luck on experimenting with your set-up. Some day you'll find a formation that fits perfectly to your team and then you'll hardly change it anymore...
