Just got around to playing this years FM and decided to try these tactics with Derby County.
Started with V2 as it's the latest one, and results were far from great. Out of the first 8 games I won 3 drew 2 lost 3, losing to Millwall and Yeovil amongst others and two of my wins were last minute winners against 9 man Blackburn and 10 man Leicester, both at home.
Decided after that to switch to V1 at half time in a match with forest which I was trailing 3-0. I came back to draw 3-3. After that result I went on to beat Ipswich 8-1 and Leeds 5-1. That's as far as I have got, but will keep you updated.
So make of that what you will, I will be continuing with V1.
