i'm just the opposite Hops, i could never get the groove going with DB rows. i always felt it in my shoulder more than anything else.

once again i agree with Eric, pullups/chins should be part of the main group of exercises done to increase strength and size, not considered an accessory movement.
imo, if you want a bigger, stronger back (which will in turn help you get a bigger, stronger front!), pullups/chins and rows are essential.

and chins will build your bi's better than any curling movement.

just my $.02
