I think the gold will look better also Bunk. Def compare the 603's to what you have. The low tension didn't do it for me and they don't detune well. But, that's just my ear and I need tension cause I beat the strings. They might be better with a pick player.
The CK's feel pretty low in tension anyway so hopefully not a big change. I don't usually drop tune except the B to A. I actually keep one bass tuned ADGCF and another CGCFBb with the proper gauges to try and keep tension even across all the basses. I think you're right though, the lower tension would be more noticeable with fingerstyle.
