Center Mounting Skis

So I got my first pair of twin tips last year - the 158 Rossignol Scratch Blast. I didn't really know much about park skiing at the time, so I kinda just told the guys at the shop i spent a lot of time at the park although it would be my first season ever using twin tips. In the end, they mounted them "modern".

Now that a year has passed, I've learned a lot more about park skiing, and I started to wonder - should I center mount my skis, or leave them where they are? There are three mounting lines on my ski - standard, modern, and addicted, standard being the farthest back and addicted being the farthest forward. Now I spend most of my time in the park although I do ski all-mountain too, so I'm not sure exactly which line would be best for me. Another thing is, that "Addicted" isn't true center - it's actually a few inches back from center. If I were to mount it center, would I want to mount the true center, or on the addicted line? Also, this is my only pair of skis since i don't think I can convince my dad to buy me two sets of skis. Which makes me think that I would want to mount my skis a little back from true center anyway. So should I get them remounted on the addicted line? Finally, what's the difference between "regular center" and "true center"? I'm assuming "true center" is the actual center of the length of my ski, while "regular center" is what my addicted line means, but I don't know what "regular center" is referring to.


Thanks, and sorry for the long winded post!

Crap sorry for the double post but I just realised I should've probably posted this in the "gear talk" forum... could someone please move it or something?

Thanks!

Yes I realize this, and I did search, but it seems as though different skis behave differently while center mounted and I was just wondering if anyone had experience with my specific ski.


Thanks for your input though - also, could someone please delete this thread? I have two copies of the same thread by accident.

it sounds like the "addicted" line is maybe centered on the center of the sidecut aka the narrowest part of the ski. that sounds like the best place to me. my old chronics are mounted way forward of the predrilled holes but are centered on the narrowest point on the ski. i think if you mounted forward of the narrowest part would make them ski really weird

Okay so I took some measurements, and it looks like the "addicted line" is pretty much dead centre of the running length (so length excluding tails and tips). It's about 1cm back or so, depending on how you measure so it's pretty much perfect for my needs. Also, as for narrowest part, if you're talking width wise, all three lines have pretty much the same width.


Thanks for the input guys, I think I'm gonna remount it on the "addicted" line :D

The addicted line is probably about 1.5 cm back and the next one is probably 2.5 back,
if you ride park only with a bit of all mountain deffenetly go with the addicted.

yes not only that, the rise of the sidecut is also the balance of the ski. For the what you are wanting you want to be mounted near where the actual peak of the sidecut is, the narrowest part of the ski on a non rockered ski. The ski has a center that is simply by measurement and then the center of the construction of the ski. you want the ski to perform so you wont want it mounted per say 5cm from the actual middle measurement of the ski but also you don't want it at actual center of the measure of the ski for your needs. you probably would do well at -3cm or -2.5cm .

just put your ski on a table or the ground and look at the side of it you want to be a little in fron of the highest point of the sidecut where it peaks you would find that the actual center is well in front of peak of the sidecut, you want to go somewhere between actual and true center

well

i had my park skis true centered and its was what i used in the park and all mountain, so if your worried about not being able to ski all mountain as good in my opinion you can only feel a difference for like the first day and then you just get used to it.  You won't be able to ski powder as good but still its not like you won't have fun in powder on them.  I ski alyeska AK and i've skied my true centered K2 extremes in the powder and had a blast.  The upside is that the swing weight is deffently at its best when its at true centered,  you can slid rails better, butter better, ride swicht better, and this is an opinion but i think skis look way cooler when your feet are in the middle of them

So i guess if you want to have a way better park advantage by sacerficing a little less floatablity and all mountain rideablity(slightly) you should mount them True center.  its up to you and the way you want to ride.  Oh yeah if there completely semetrical (exactly the same in the back as the front) deffently get the true center mounted.

anybody who read this feel free to disagree but this is just what i think based on my experiences

Okay so you're saying that there's the center measurement (length of ski divided by 2) and then the center of the construction which is where the ski is the narrowest, and that I want my ski not on the exact center measurement, but I don't want it too far away either, right? So I would assume that the Addicted line is probably about perfect for me, since if my measurements are right, they're about -1cm from center?

One last thing, what's the rise of the sidecut?

Thanks for taking your time to help!
