True twins or directional twins?

Whatever works for you.

Based on all of that you are absolutely right. Don't get symmetrical skis and don't center mount your directional skis. That way they will carve a lot better.

true twin implies the tail has the same rise and height as the tip, not that it is symmetrical

get snowblades

I've been dedicated to skiing for the past 3 years.
First season I started off on directional twins. It was not a "true twin" either. Dimensions in the tail were much more narrow and the tip didn't rise as much as the tip. Mounted about -2 from center.

The past two years I've been shredding a true symmetrical twin mounted dead center.
For my type of shredding, this is the type of ski I've dialed in. MUCH easier skiing switch, better balance on rails and in the air.
I use this type of ski for mostly park and the occasional groomer and tree run.

I'm investing in a set of either JJs or Kung Fujas next season which will NOT be mounted dead center. Most like -2 again. It really just depends on the type of skiing you do.

ya

You are very right. I love center mounted pow skis and park skis any day but when it comes to fast piste, park runs, bumps, and the occasional mild powder day, it's nice to have a slightly negative mount. Head john 94s are what I use and they are dope. They were cheap but they last forever as far as I've seen, and are not a breakable construction. Kind of an unknown ski. Watch 10 year old videos of pro skiers, like Ski Movie, and they did a lot of the tricks that are still popular today, on directional skis. "oldschool" design works fine for most of the tricks NS is really gonna be doing first year or two in the park anyways. Get real you guys, skis are skis, they just want your money every year to make you way better at skiing.

You don't need a symmetrical twin to ski switch as long as it's not that far off like within 5 or so mm. Anything more and it may or may not make a big difference due to your level of skiing but either way it will work perfectly for hitting features switch or landing.

Honestly I'm a fan of treating my all-mountain park ski more like a park ski than an all-mountain. By that I mean I'd still mount it center or close to to benefit the park skiing. The reason I do that is I feel it makes a more positive impact in the park than it does a negative impact outside the park. I'm sure you will have far more days in the park on them than in the powder.

It dosnt matter to much just mount them dead center

Then you have more tail than tip (on a non-twin), moron.

true twins are the worst if you do anything outside park...if your mountain has any sort of decent powder/glades situation that you like to hit dont get true twin even if you do spend most of your time in the park.
