Definitely get the 161's. Especially if you are planning to center mount the ski, because they will feel a lot lighter and shorter when they're mounted center. 151's would seriously be too small.

Either would work, but the Olsson are super soft.

olssons.
hands down.
just look at who Jon Olsson is and what he does.
plus, salomon has had a few issues with edge construction. and Head is one of, if not the most repected ski companies on the market.

probably the dumonts. don't know a whole lot about the olsson's but the dumont has a really good reputation and a solid construction.

Wall.
it is one of the best twins ever designed.

The Dumont. Its just more stable underfoot.

dipends what you want to ski dumont is park specific with still good all moutian performance (just like the salomon suspect) and the line anthem is park specific but is really wide (93)waist and isn't great for all mnt or high speeds...idk about the chronics or the t-hall but the ar6 is also a park specific ski that is really good for all moutian too...if u ski all mnt more then park go for ar6 ...if u ski park alot and some all mnt go for dumont and if u ski JUST park go for anthems

line chronic, armada ar6 or 4frnt tnk all great skis. also the salmon supects r great for jumps good for all moutina...and if you change you mind you can still do rails with the suspect too...overall i think the suspect is great for jumps jibs and crusin all over the moutian too

Simon's first pro model, the ones that came out last year with the sunset on the nose and such were all wood core as well. The older spk's and foils and such were the one with the foam core. But these new ones have awesome sidewalls and some sick pop
