Ive got myself a pair of blue tuff 1's 

 i actually do like these 
as they are a little different from the normal II's they are as heavy 
as Kerry katona after a binge at Iceland 

 but they are straight 
with no nicks.
so when were tuff 1 produced?
why did they not take off? was it because they were to heavy?
do they use the same bearings, and axles as the II?
and can they be dyed the same?
