I agree that ramp angle is the valuable information but pin delta is the only thing you can measure without bringing a whole lot of other factors into play. Ramp angle is:
Code:Ski thickness toe + toe pin height + "front boot inserts" (inserts location, bootboard, liner etc) - Ski thickness heel + heel pin height + "boot heel inserts" (inserts location, bootboard, liner etc) = Ramp angle

As toe and heel insert hight are fairly standard (albeit not an ISO standard unfortunately), I think it's fair to use ramp delta, as it can be calculated by pin height.
Plus it allows a direct comparison with alpine and frame bindings.
Of course there are a few boots that vary. But weird variations do exist also for Alpine bindings (actually, the most odd candidates are generally performance/race touring boots in my experience) and it's more important to know which boots are odd. Because that knowledge is anyway needed, regardless whether pin height or binding ramp delta is being used. And it allows to compare with other binding systems.
Binding ramp delta is also independent of ski or boot.
Real ramp angle between the ground and your foot is a different thing, though and of course depends on the whole setup.
Ramp angle is most sensitive to BSL changes. Of course different types of boots with their foot bed ramp angles play a big role, too.
But I'd neglect ski thickness entirely. I don't know a single ski that differs significantly in thickness over the stretch where the binding will be mounted.
Ramp delta is the number that allows best cross-binder comparison. Period.

After ordering the IONs I had some time to kill while my daughter was at dance class and I went to the shop next door to check out the ION again. They are really nice when put next to Radical ST/FT, I don't really see any downside to these bindings over comparable offerings from Dynafit. Very easy to operate. I can't wait to try them on snow, I'm putting them on my older pair of Lhasa Pows.

Just saw a pair of ions mounted. One worked ok, the other one wouldn't stay open in the toe?
Maybe a bit early in the product development process?

Worked like a top. Thanks for the heads up.

Agree, which is why I wrote "a pin delta of 10-11 mm feels about 'neutral' and similar to the mild ramp of a typical alpine setup. so I think the g3 Ion pin delta of 11 mm probably support their claim of "3 degrees (or 'neutral'), matches ski boot mfgers intended angle". " in my post above.
I still don't know what the approx height in mm from the topsheet to the top of the tallest Ion heel elevator is. Alpinord, I had already referred to that product spec but it just says 14 degrees High Lift...G3 forgot to mention what boot BSL that angle corresponds to so it's a somewhat meaningless number. All I'm looking for is a qualitative comparison between Dynafit and Ion in the max elevator position.

totally. the uptracks there are steep. lulz.
OK so G3 emailed me and said the distance from top of 'tall' elevator to ski topsheet is about 80 mm (my vertical STs are about 84 mm). With a 322 BSL boot, and the 5 mm shim under the toepiece that many of us prefer, the vertical ST has a boot angle of about 13 degrees. Since we don't know the BSL of the boot G3 used to reach that '14 degree' spec, let's assume it's shorter than my big feet...and since 80 mm is less than 84, that seems like a consistent assumption...so apparently the Ion tall elevator is not quite as tall as the Vertical's. If I get some Ions, I guess I'll have to make some shims to attach to the elevators.

Skied mine for the first time today in that awesome ice crust at vail and never had any issues.
Can't wait to get to and tour with them.

Mounted mine this am, the SlideWright template is perfect. I'll get out and ski them this afternoon or tomorrow for sure. These are really refined looking and function bindings to my eye. I really think G3 took their time with these. Even the little cover over the brake springs is well thought out, a place that often sees icing if you're using brakes with Dynafits. I guess that's not an issue if you don't use brakes but it's nice.

how does the top plate of the heel piece attach to the main body, from picts' it looks like the screws come up from the bottom and thread into the metal top plate which should be a better idea than threading into plastic like dyanfit and plum especialy with the stresses the flippy heal lifters put on that top piece ?

Are you blessing the template as confirmed, Aaron? Glad it worked.
Here's a time lapse on cutting and splicing for various BSL:

Cool. Thanks. I got the toe & heel to hole dimensions from davieboot. With a G3 ION Jigarex plates due in the next week or so, I'll also double check the template relative to the plates. For my Maestrales RS's, I had a discrepancy between stamped BSL and horizontally measured BSL, which the Jigarex plates are relative too.
