IMO, they're either going to explode if they make a very noticeable difference in skating or die out just like other failed technological "revolutions" if the don't work or if any difference in only marginal. I was already out of the game before composite sticks completely (or nearly completely with the exception of some old-timers) replaced wood sticks, so I didn't witness how long that transition took to filter down and become universal; but that seems like a comparable example. If composite sticks only made a slight difference, there wouldn't have been much of a market for them beyond the most elite levels where players don't pay for anything and where even the slightest advantage is worth paying around 5x to 10x more for each stick. The last time I played before coming back 4 years ago, there were only a few guys on my team even using composite shafts and replaceable wooden blades. How many wooden sticks (or blades) do you see nowadays, even in recreational leagues and pickup? If these things work as advertised, they're a lot cheaper compared with what everybody's skating on now than composite sticks are vs. wood sticks. Of course, if they work but don't hold up under playing conditions, then, they'll probably be used primarily at the elite levels (assuming they're approved for use) where neither cost nor inconvenience is an issue, exactly as suggested by Santos and others.
