Thanks again for the feedback guys.
I suppose I'll hold on to it for the time being then. I was pretty concerned mostly cause I went over to a shop a few days ago, and the guy there told me that 163 is way too big for someone my size (6'0, 180 pounds). He said I should be aiming for 159 up to at the very max, 161. But, according to here, 163 should be okay then?
