In reply to Haggis Trap:My point about your posts are that they are very one sided, and at times a bit rude, don't think I am patronising and I don't think you would call me a clueless punter to my face, so don't do it on line.
I see you have changed now to most instead of all pre releases are due to user error or icing, thats the whole point, Dynafit are prone to pre release and all these checks do minimise this, but still those responding to the article above are citing examples of prerelease even when they do this.
I see you don't cut and paste in the last point of the article where Lou says that Dynafit don't suit some styles of skiers and size of skiers, i.e. those that are likely to put most pressurise the binding, large aggressive skiers, in which case the advice seems to be lock them or, change binding. As I would fit into the group being likely to have prerelease I don't want to have a binding that I have to lock out.
Having skied Fritschi for over 20 years I have never suffered with this sort of pre release, nor do I have fiddle about clearing boot holes of dirt snow or ice. So while I understand the advantage of Dynafit in terms of weight, for me the disadvantages outweigh the advantages, possibly because I climb and tour all the time, live in the mountains, I don't have trouble keeping up with people on lightweight gear, so the weight issue means less to me. It's good for my fitness anyway.
If you look at the replies to the article, it's clear this type of skier does have problems with Dynafit, see the responses…
Skian, my Dynafit work well, I am happy with the bindings. I did say that I make Dynafit work. I am a 230 lb guy who makes four different Dynafit binding models work. I am strong enough to release the bindings, and as an example I stated that I did it with Fritsches as well. I tried to say that if I ski smoothly, which I do, I have no problems.
In spite of that I can generate enough force easily on hardpack snow and wide skis to open the toes of Dynafit, so I need to lock them on hard snow- except on my narrower skis 70 waist and 80 waist. but on 88 waist, 95 waist and 106 waist, the toes open easily with my weight/strength on hardpack. And, as I said, locked, clean, proper functioning, I am able to twist out of Dunafit toes.
The release is smooth, well-engineered in my view. The Radical, I believe, was designed to prevent the opening of the toes by downward pressure.
My intent was to share my experience with big strong guys on Dynafit bindings.

@Skian: The reason the dynafit prerelease get attention is that it different than other prereleases. I have skied since I was 1 1/2 and is now 40, so I have experienced unwanted releases with a portfolio of bindings. I have toured with dynafit since 2000. The other prereleases are vertical or horizontal, and is usually due to too low RW settings or a broken binding. The dynafit prerelease seem to be more of a “diagonal” release – i.e. something that is not possible on desgins where the toe only has the opportunity to slide sideways.
'I agree that the tips above will eliminate most of the prereleases – so there is no doubt Lou is helping a lot of people with it. But, on ice I still prerelease – and the RV setting does not affect it. I don’t have to ski hard. The one thing that seems to help me on ice, is to use shorter skis with more sidecut. I think the reason is that I can use modern race technique to get down without slarving/sliding. On straighter skis I have to put more force on one ski in order to bend it (i.e. more 90′ish style technique) – thus making a prerelease more likely. The other aspect might be that waist width affects the prerelease. On wide powder skis on ice, I will prerelease in walking speeds, while on narrow skis it has only happened when I have been doing SL-style turns – and even then it does not happen often.
So – when I see blueish ice (e.g. glaciers, frozen streams etc) , I now lock the toe, or head over to softer terrains where it wont be problem. "
Lastly it would appear that those most at risk of pre release are those putting most pressure on the binding, so it appears to me inexperienced skiers might also be in this category as they could put more pressure on this type of binding, and be less likely to have the knowledge to be able to check the bindings properly, but thats just my view I am no expert.
