Dynastar's all mountain offering for the 2019-20 season is fairly minimal and seems to consist mainly of adding the vaguely adventurous term '4x4' to the name of a piste ski.
Perhaps that's a flippant and cynical first impression of the Speedzone 4x4 78 Pro, but as it turns out, it's a fairly accurate one. The 'Pro' designation signifies the presence of a titanal sheet, but any added stiffness is undone by the light wood construction. For the kind of skier that might want to dip their toe off the side of the piste, such a lightweight ski isn't likely to inspire confidence as it's is very easily deflected, with no power to charge through crud and too narrow to provide any real float. All this adds up to a ski suitable for a strong recreational to intermediate piste skier who might enjoy one early morning run off the side in a very light layer of fresh snow.
It's much better to approach the Speedzone 4x4 78 Pro as an affordable piste ski and on that basis the relatively soft flex makes for a fun ride compared with stiffer, performance oriented piste skis, and with good turn initiation.
At £495 with bindings, the Speedzone 4x4 78 Pro at least is good value for money, so if you're looking for an entry level first buy for 95% piste riding with very brief diversions off the side it's worth consideration.
