Replying to Are 160cm skis too short?

I just picked up some Original 02/03 Armada AR5s off ebay, new, for 120 bucks.
Not really a bank blowing purchase, but I do need something to get me on the slopes before I can invest in something in the 350-550 range.

Now onto the real thread.
I'm 5'11'' and about 145 lbs.
I used to be a pretty good skier, but rode skiboards for the past few years.
I know that these skis are "short", but how short? Will it put a seriously damped on my skiing?
I normally hit rails and 15-20 ft tables, little powder, and a lot of groomers.

I'm planning on having these be an all park ski, as that's all I ride because of were I live.

How will these guys hold up?
