I don't have enough experience to say whether they are good or not. Do seem like decent connections and the pieces do make it more manageable (but none of the pieces are light).
But a side note - in the second video listed (http://www.youtube.com/watch?v=KfCmIjmA9nI), I am the second 2 last paddler (black paddle). That was from Outdoor Retailer 3 years ago.
They have since done a longer version with LL Bean - I think 100 paddlers. Must have been a beast to turn around. Was hard enough with the 9 or 10 we had.
