Replying to ARV in park?

I was planning on getting T-Halls, but the shop doesn't carry any so demoed some ARV's today (I can get last years for cheap). They did great in powder/tress and I did a bit of park and they felt really light on the few jumps and rails I was able to try. Anyway, before I decide whether to get them or not, I ski a lot of park and was wondering if anyone who had more experience on them then me could tell me how they hold up in the long run in park?

The only other thing is I'm 5'11" and 155 lbs but they only have last years in 175, that's the size I demoed and it seemed fine though.

Thanks.
