I am curious about the Epoxied anchor bolts.  Do the instructions have you 
drill the holes for the bolts and epoxy in a way that the hole in the 
concrete,  is lined up in the direction of the pull?  Or is the axis of the 
user drilled hole, NOT  collinear with the force exerted?   Can the bond of 
the epoxy and its smooth walled hole in the concrete withstand the stress?   
Actually,  I think the bolts themselves have some sort of a sliding wedge 
expansion feature too, which would also share a piece (maybe most?)  of the 
force exerted...  Just curious...
