Wow! Three different type bearings on one tip? That is high-tech!
Three bearings may increase a little the friction but I guess they will make the top much more sturdy. I want one of those sooooo bad!
The one-way bearing is going to be great to popularize top play (except for the price). And contrary to Duncan we know you ARE going do deliver!
(but I bet Duncan will feel forced to put out the aluminum one-way BK once you start selling them).
Personally, I don't have a problem with the current tip and upside down tricks.
