I guess what you do with the information is the biggest thing.
You're going to need more than a thin pencil!
Anyhow, I was also at Snowbird for the Campbell Dynamic Balancer (CDB) demo and I've also been thinking about building my own.
The key things that Steve Bagley stated are interesting discussion topics:
- The skis used during the balancing measurement don't matter - he uses the same pair of skis for everyone. They just have the center of running length marked on the ski (this is lined up with the fulcrum of the CDB) and then they had some measurement lines that are read off when aligned with the front of the boot toe piece. The skis had velcro (just the soft side) on them to help keep the boots from slipping, but I would think that rubber would do a better job.
- Binding weight doesn't matter - the extra weight of the bindings do not sufficiently change the balancing enough to worry about.
- If you change boots you must be rebalanced, but you can change skis all you want - you just need to know your "number". Let's say you're a "9" that means the front of your boot toe should always be 9cm ahead of the center of the contact length. Steve said that as long as you're in the same boot this measurement transfers to any ski.
So I'm not so sure I agree with all of Steve's assumptions yet. I guess I'll just need to build one and do my own test to see if it's true.
The one thing I did figure out when messing around with the balancer is the answer to "where is the BoF exactly on my own foot". This has been discussed before, but what I found is that it seemed to be the point right where my arch ends and the BoF begins. I was using a point further forward on my foot before this. This moves the BoF back closer to the midsole mark on a boot and I found that when I lined up this point of my foot on the center of the running length everything felt very balanced.
