I’ve used Dynafit bindings for a while and had planned on putting them on a pair of Soul 7s that I just purchased. Specifically, I was going to put on the Radical FT or ST. I have to say that I have found the Radical ST to be good and I like it much better than older versions like the Vertical. However, a couple of folks recommended the G3 Onyx, so I’m considering them. These are the basic specs according to the manufactures (prices from Backcountry, but I’ll buy from my local shop).
Weight Price “DIN”
G3 640g $439 6 – 12 - weight does not include brake = 136g
FT 599g $599 5 – 12 - weight includes 110 brake
ST 531g $499 4 – 10 - weight includes 82 mm brake
For me, the draw of the Onyx is the price and the ability to go from tour mode to ski mode without removing boot from binding. According to WildSnow, another design feature that G3 touts is elasticity in the heal, it supposedly will return to center after a shock. There also seems to be some elasticity built into the toe piece. Some on TGR suggest that this elasticity helps prevent pre-release when on chattery and icy surfaces.
The downside of the Onyx is the weight and some of the reviews. While the reviews that I’ve read are mostly good, there are some that are downright bad and it is the not-so-good reviews that worry me. For example, a reviewer from Backcountry Skiing Canada suggested that he “found it difficult to adjust the tour mode lever (the round unit off the heel) with my pole. Actually, I found it impossible. I’ll bet I could figure it out with practice.”
More worrisome is the one from a MEC user… “The problem is that while G3 has made a beefy enough binding, their bolt pattern is far too narrow which puts tremendous torque on the toe bolts. Both of us ripped our bindings out of our skis within 1 week, destroying our new skis. To give some more context to the situation; we both bought brand new skis in different sizes and brand and had our bindings installed by different stores. Mine were even mounted on a pair of G3 skis. We are both medium-weights (I'm the fatty at 185lb) and we ski at a moderate to advanced level. Furthermore, I was sad that G3 did not recognize this problem and had no interest in helping us as loyal customers…. An additional flaw is that the screws holding the binding to the mounting plate simply screw into the plastic in a 'self-tapping' way. I am concerned that this will not hold up to regular switching between skis…..These bindings, in our experience, are not appropriate for skis over 100mm or heavy skiers or advanced skiers who want to push hard. Until G3 comes up with a bigger bolt pattern, I do not recommend these bindings. I hate writing bad reviews but I hope less people will get burned the way we did.”
So, after that longwinded post, what have been your experiences using the Onyx (in particular) versus the Radical?
I didn't discuss the Radical because I know what to expect.
