yes, 4-5-1 V style is a very useful formation. Try to have a very good AML and AMR so you can use this formation.
And a good AMC and DMC are absolutely necessary for this to work. To beat most formations, I find the 4-5-1 V, 4-4-2 narrow diamond and the butterfly are the 3 formations I use the most. so the AML/AMR/DML/DMR/DMC positions are very important to me.
