Great work!
I think your 451V is in good settings and shape now. It is all about taking time to adapt players into their positions and get familiar with each other' role and position.
I hope you can use it to win a treble then it would be a classical strategy to train and use 451V, which you might want to write more about how you trained and used it etc..., which will benefit other users whose favorite is also 451V, such as me :-)
