Informative review. Couple of comments...

1. Interesting that you are also using the BD Quadrants. Two of us have noticed the same problem with toe clearance with Quadrants and the Plums. We both have used tech bindings for years, but find that the Quadrant is a bulky fit with the toe pieces, something that isn't a problem with the Dynafit tech bindings. I've actually used permanent felt to mark the positions on the toe of the boot so I can be sure I'm stepping in at the right point.

2. If you are using a soft ski (i.e., DPS Carbon), set the heel clearance carefully. The flex of a soft ski can cause the boot to fully contact the Plum heelpiece, fracturing the polymer block. Plum is aware of this problem, but chose not to inform public because they apparently believed it would be a rare occurrence. I've seen three heels blow in a two week period before the info came back to ski techs in the Whistler area and adjustments were made. Plum fully backed the replacement of the heel pieces, but users still lost ski time waiting for the replacements.

3. The ski brake (non-optional) is an issue. These are touring bindings, and some will continue to tour without brakes, risking losing a ski in the backcounty. At the same time, leashes should not be considered an option in avalanche terrain, so what to do?

Hi All,
to reply to Rebob's post, it is correct that PLUM has not informed public about fractured polymer blocks, inasmuch as it has been a very isolated issue (4 cases among thousands of pairs).
It is important to note that 2 of these cases were due to improper mounting, with an insufficient heel clearance.
Even though improper mounting is not covered by the warranty, PLUM has replaced these free of charge.

As for the front lock lever, it has been fully re-designed, in order to suppress this release issue with certain models of boots.
Owners of current Guide bindings can have them upgraded with the new front lock levers.
Just send me a PM, and we'll organize this.
