I along with 90% of the people responding to this thread - have only owned one of the brands.
I have a pair of Bluehouse Antics that have been around for their 3rd season now. I've owned three other park skis along side them - which have all been retired/snapped. I am extremely happy with the antics - they have a TON of pop and the edges have held up extremely well. I will continue to use these skis till they completely die.
I have no input on on3p, however, seems as though majority of NS roots for them.
your just lucky your not me. i forget what i'm talking about mid sentence..... it's entertaining... - bombin_baker*
