I purchased the Supershell system last year and the heel stabilizer on it cracked twice. I know I am not alone in this experience, as some skiers at Okee had the same problem. Reflex tells me they are aware of the issue, and sent me a third heel stabilizer which appears to be a very inexpensive piece of plastic. I love the Reflex system and I used the original system, including the R-style rear boot, for many years before buying the Supershell. But I can't say that I think the new system is better (though I do like the double horseshoe in front), and I certainly don't think it is worth its cost. I did rupture my Achilles in my original system, but can't be sure it wouldn't have happened in another system because it was a strange fall. All in all, I wish I had just stayed on the original Reflex system, which is an excellent binding system.
