Scotty, et. al.: The 2% number is what the Total Seal folks quoted me
over the phone (as well as what Chris told me) for their ring. They do
only the second compression ring; one assumes you'd continue to use the
top ring as provided by the ring manufacturer. As for benefits/
tradeoffs, I didn't ask. (Guess I shoulda, huh?)
