Thanks for this!Tried the range, and they are really nice. Just for those who are coming from the current ZX5, maybe you may want to take a look at the ZX4 MK2 before ordering. Looks like the ZX4 MK2 are the exact same sole width wise as the ZX5 current model. Only difference being the blade length being longer. Currently using the ZX5, but will probably give the ZX4 MK2 a whirl instead of just going to the ZX5 MK2. The feel is different, feels a bit like the P790, a manufactured kind of softness but really feels like its got a lot of pop.
Summary:
ZX4 MK2 = same size and sole width as current ZX5 but longer blade length. Also looks like it has less offset
ZX5 MK2 = looks slightly smaller than the current ZX5 and still feels great, but seems a little bit less forgiving than the current model
ZX7 MK2 - did not hit this much, but a buddy did, he is coming from the current ZX7, says it is a touch less forgiving, but feel is more solid now
Does not seem like the ZX MK2 series are a direct replacement, would seem they have made them a little bit more for feel and for workability than forgiveness, just a little bit
