A Simple Fore/Aft Balance Test - What Does it Mean?

post #1 of 4
Thread Starter 
(Posted both in "Ask the Boot Guys" and "Gear" forums)

I have 2 ski setups that cover my needs very well. The first is a pair of Metron B5’s with Neox bindings and the second is a pair of Sugar Daddy’s with Freerides. I am very satisfied with these except for 1 shortcoming: I find my stance/balance with the Sugar Daddy’s setup to place me a bit in the back seat and require some extra effort to maintain good fore/aft balance.

The total delta (including combined binding and ski “delta”) for these 2 setups (my first consideration in thinking about this) is surprisingly very close. So I looked to mounting position and ski balance point (something like a Campbell balance does). As a test I put on my boots and, using a large dowel, found the balance point where I could equally rock the skis forward and back using only foot movement and no repositioning of my upper body in the fore/aft direction.

Results: The balance point for the Metron setup was just behind my forward boot buckle while that for the Sugar Daddy was in front of it. There was probably about an inch difference. I need to repeat this a few times as there is some subjectivity to the measurement.

I have my own interpretation of this but am very interested to hear what people think without biasing the discussion.

Note: For those who think I’m crazy please note that this is the off season and that I more than happy with these setups

This means that for your Daddy's you'll have to put more power to the tip of the ski to get the equal "performance" as for your Metron, right?
I'd say that on freeride skies the balance will be back because you want to have the tip out of the snow, on a carver you want to get fast into the next turn.
Then I believe that the Diamir Freeride will have BP behind the skies BP and as a result you could, if you want to achieve the same feeling, forward mount the binding, maybe not by an inch but maybe 1/2 an inch.
I've done that on my rando skies because I feel that I don't have the same forward lean in my rando boots (to prevent that my BP don't get behind the skies BP)

Saw your post here and in the boot forum, along with the responses.

Depending on where your first buckle falls in relation to your BOF, do you really want a BP in the same location for two entirely different skis?

Are you using the skis interchangeably for the same conditions, or dedicating the Metrons to "on-piste" and the SDs for less tracked conditions? It really is an experiment to find what feels most comfortable and responsive to you, but the more rearward mounting of the SDs should favor fresh snow and "natural" conditions.

Sounds like you're following a logical path to engineer the feel you're looking for, so now it's just a matter of finding it. Will be interesting to know what that is when you find it. Hope you find it soon ... the season's here!

Saw your latest post in the boot forum.

Haven't given this an in-depth analysis, but since the setups are dimensionally so close, the "dowel test" you did originally may not relate very well to the sensation you're experiencing on-snow.

Meaning, on snow you're not balancing on a fulcrum. The CRS isn't necessarily the center of balance for a ski. Depending on the amount of material in the tip and tail, a ski may or may not balance at the CRS. Since you were intentionally trying to remove upper body from the balance exercise and just trying to balance at ski level, imbalance fore/aft of the ski could play a role in your test that wouldn't be a factor when skiing.

The setup being so close dimensionally suggests to me the on-snow "balance" may be more related to the ramp than distance from CRS -especially if you aren't talking about floating bottomless fluffy stuff. ...just thinking aloud...

A part of it might also be ski design. On firmer surfaces, the metrons are going to hook up more aggressively than the SDs, giving you faster tip response and the sensation that you're more forward.

Hope you find the "magic".
