PS: How much difference would there be (body-wise) with the French set - which they note will be more "active"? Does this mean buy a box of each and head swaps would give you more dynamic archer units on the move, and then a set of steady archers in block?
I guess so. Mixing and matching always provides the best result. A single set is always going to have its limitations.
That said, I'm reserving judgement until I see the English men-at-arms frame which I'm sure will be more 'active' and less static.
As I say though, I think if you look at the previous plastic output of the respective Perrys, it may just be that Alan prefers a slightly more regimented stylised look (see his Naploeonic, AWI and ACW sets), whereas Michael likes a more dynamic, varied, skirmishing look (see his WOTR, WW2 and Sudan sets).
Different strokes

Still think it's going to be a brilliant set. Can't wait.
