The sticks that you saw during the playoffs and most of the season that were breaking, was the Easton Synergy. The most expensive stick on the market by far, but obviously not the best. You can't dislike every one-piece stick there is just because Easton's went bad. CCM has made a very good quality stick that will be able to endure professional level hockey.
As for the Advantages of having a one-piece stick over a wooden stick. First of all, you may be able to buy 12 wooden sticks for the price of one composite stick but, you'll go through probably at least 8 or 9 wooden ones before the one-piece stick would wear. The number of wooden stick broken would vary depending on how you used the one-piece. Secondly, who wants a big, heavy stick to carry around when you can have a light weight, flexible stick that can with stand shot after shot.
Obviously for young hockey players it would be completely pointless for their parents to buy them 200 dollar sticks when at that level it doesn't even improve their performance.
