  We show that the dual Abrikosov vortex between quark and antiquark in Abelian
Projected SU(2) gauge theory is insensitive to truncation of all loops except
the large monopole cluster noted by Hart and Teper. As the transverse distance
increases, the discrepancy decreases, suggesting that the London penetration
depth determined by the tail is invariant under the truncation of short loops.
