I'm a PPSEL also, training for my IR right now. We had some icing on my last flight that caused some pitot/static issues, fairly quickly solved by flipping on the pitot heat and climbing out of the clouds. Very interesting psychological experience; I had to use a good deal of mental energy to shunt the terror out of the way and used what little was left over to fly the airplane.

I've come to the conclusion that dealing with those situations is analogous to lifting weights: when you start out your ability is weak. Experience and training increase your strength but there is an upper limit. You just gotta hope you don't have to press something that's beyond your max. The likelihood can be mitigated against but not completely eliminated.
