Was fooling around with the latest production Dynafit FTs a few days ago, and realized we’d not yet published a comparo to previous year’s itteration. Both bindings are virtually the same, with a few small differences. Probably due to thicker steel in the toe wings, the newer binding toe weighs 14 grams (.6 ounce) more than the older. The toe wings are said to be stronger (let’s hope that’s true, to make those 14 grams worth it), but my understanding is that most of the difference in appearance of the toe unit is cosmetic (mainly, the small ribs on the toe wings). The heel unit remains exactly the same as far as I could tell.

09/10 Dynafit ST binding has a few small changes, weighs slightly more.
In photo above:
1- Thicker toe wings are slightly stronger, and previous ones did break on rare occasions.
2- Larger access hole for front screw, this is the best change as far as I’m concerned.
3- Tiny steel tabs are thicker, I’ve seen a few of these fatigue and break over the years.
4- Steel here is slightly thicker and perhaps a bit stronger.

Best change for the new ST is the screw driver hole actually fits a standard insert bit. For previous bindings, you had to modify the bit by shaving off a few hundredths of diameter or it would get stuck in the hole or not align properly with the screw.
Weight 09/10 toe, no screws, 6.5 oz, 182 gr
Weight 08/09 toe, no screws, 5.9 oz, 168 gr
