That's the whole point mate. Different tactics seem to be working for different people. Your question is a bit vague. I was having no luck with crags version which other people suggested was the best. Its probably best to go through each one till you find one you like and works for you. You dont need to start a new save for each tactic as the tweaks for each version are barely anything.
However to answer your question. I am having success with alex's 11.3 tweak, i am using man utd, with players equal to the quality of barcelona.
