One item to consider is the bindings themselves. I used to have markers but they pre-released when I would hit a bump with low impact. The old Markers always had issues but I have heard their Royal family is good.
I went to a Look/Rossi binding b/c it has some "give" with the elasticity travel, never had the problem on low impact hits. Recently, I've had pre releases when I skied more aggressively on hardpack, so I turned it up one level and never had an issue since. And yeah, I did spin out bad when I skied in and out from an icy section in the mogul field.... it released as it should with out twisting my knee. In my case turning it up to .5 to 1 was not a big deal.
