Will is *not* under-stating the reliability of the roller chain track 
... it is built like a tank (no pun intended).  It is practically 
impossible to damage it and there appears to be no way that it will come 
off of the sprocket in normal operation.  In fact, it is hard enough to 
remove after all of the tension has been released from the drive wheels.

Although I invented the bicycle track approach when I started building 
my Tiger, and feel obligated to keep using it on that vehicle for 
tradition's sake, I am fairly certain that the next tracked vehicle that 
I build will be using the roller chain. What you lose in increased 
weight is easily made up for by increased reliability and performance.
