What a load of bullshit. The Mounties do not advocate hiking up Si in plastics. They do define as being in shape enough for the course as being able to hike up Mt. Si with a full daypack in 2:15.
The Mounties also insist in their course docs, "Plastic boots are great for glacier climbs, but not suitable as your only climbing footwear. "
A good climb leader for the Mounties will recommend students *not* to wear plastics on climbs like Eldorado.
This thread just sucks by now. Do what you want.
BTW, GY, trolling you is so easy that it's boring.
