Once upon a time, I did have the spray skirt with my yak and it was worth the investment. Not so much for the fact of staying dry during August showers, but surviving a roll during May hypothermia season. Needless to say, you will broaden your yak season with a skirt. Once you get it, take some time and learn rolling technique at your friends in-ground pool.

As per the question, "Just what are those little rubber thingies on the paddle near the blades supposed to do anyway?" They are suppose to be closer to your hands and prevent the water from running down to your hand and elbow.
