MY perception is that the bushings are quite soft which seems strange to 
me

First, the (black bolt)pins are undersize, (pip pins are spot on and the 
bushes pretty good)
The tightness is cause by miss alignment of the bushes, both linear and 
angular. Poor jigging in the factory using the black bolts. 

Avoid using a reamer to line them up, if they are bad warm up the redux 
and remove the miss aligned ones then rebond using better size pins for 
jigging.
Just do this with the two wings, forget the bushes in the seat back, 
they really are better with a loose fit because they increase loads on 
the wings with G forces. THe glider wing is different isn't it, (not 
seen one recently)

Mine is exactly the same.  In fact, I remember before doing the weight 
increase mod I put one of the brand new bushes on the brand new spar 
pins and was surprised by how much it wobbled about.  But when the spars 
are rigged together (4 bushes in line) there's no play whatsoever when 
the pin(s) are through them all.  I think it is normal.
