My PC actually takes very little wind to play properly. Blow too hard and that is when funny things happen...

From what I have gathered.. The red Warnock reeds are easy to blow, and seem to work well in most PCs.. I use a Walsh right now, very easy to blow, good tone.. Gibson reeds are quite good, but require a good bit of air.... I have heard good things about Watson reeds, too...

Try a Warnock, you should be able to find them online for 6 bucks or less.
