I just moved a GS200 crankset to my "main bike" from my "backup bike". Although it was a severe downgrade, "quality-wise", I needed the shorter 170MM cranks vs the 175MM I was using- See-

I initially used the original BB cup & spindle set up, although the races were questionable. I then changed to a new cartridge BB and noticed these differences-
On the old spindles (I had 2 different ones) when I tightened down the arms, the bolts basically tightened down immediately and I had negligible rotation as I torqued them down. On the NEW cartridge, I could feel the arms tighten down pretty much all the way. I still had that feel when I reached what I felt was more than adequate torque. I didn't have to adjust the Fder (I have friction shifters, thus more "leeway"), but I felt the more I torqued it, the more tha chain line would decrease.
