Great, thanks everyone. I don't want a super stiff oar -- just an oar that's stiffer than the Polecats were. I know that sounds pretty vague, and it's hard to quantify.
As for fiberglass shedding from Cataracts, I heard that affects oars manufactured pre-2005 or so. They changed the formula and supposedly that no longer happens.
I also found some relevant comparison info here:
Sawyer MSX-G vs. Cataract SGG - www.ifish.net
At the end, all comes down to the feel and what a person likes. I'm going to give the Cataracts a try. Thanks again,
