If you only have one pair of skis to race and train on in each event. The skis will probably not last you into next season anyway.
That being said, any of the choices you mention above are excellent. Just make sure the prep is correct.
I can tell you first hand that each of these skis race stock or not, already have an edge grind from the factory. All of them have a base edge bevel upwards of 2 degree. This is not good, as they need to be between .5-1.0 degree. Trust me when I tell you that making sure the base bevel is correct means everything to proper acqusition of technique and tactic.
All side edges on these skis arrive to you at or around 2-3 degree, either of which will work fine. However I recommend you keep them at 3 degree on the side.
