I do lot's of photos with a #8 outfit and have found it very 
reliable, even without the power of a #10 spring. I've noticed a 
couple of things that help minimize banding. I rewind the kodak 8 
inch film so the black side of the leader is out. This lessens the 
angle from the spool to the slit. Lots of people run #8's with film 
straight from the box, but I've found I get less banding with reverse 
spooling. The steeper the angle while pulling something over an edge, 
the greater the friction. The other important thing is to wind the 
film onto the drum with the lense cap on and then rewind before 
exposure to make sure the film isn't sticking to itself as it 
unwinds.It makes a big difference. (thanks Ron Klein!)  I've been 
getting photo's where you can't see any banding, and my #8 isn't all 
that great.   Jamie
