Locating the valve hole so it falls within the widest part of your pattern is best. Try doing it the other way with one of those 650 aero rims using a long valve stem. After you lace that up then try using one of those newer pumps with the multi heads. Why would you intentionally put the valve location in a tighter spot. It even makes it harder to use big arthritic hands to loosen a stubborn valve in the cold. Besides, I have always been told that it looks amateurish.
