In "Super Heavyweights (Part 1)" in the November 2004 issue of Word Ways, I presented words and phrases with letter sums of 355 through 501 (setting A=1, B=2, etc.). In this article, the continuous run is extended to 547, but samples are given for many numbers above this (including 666!), with the expectation that readers will fill some gaps. Perhaps many could be filled (with varying degrees of satisfaction) by using the plurals of existing items; also, previous writers have often taken a noun (e.g., ending -tomy), then tacked on various verb endings.
