I think my msx-g's are 9'4" and I've got the Dynelite blades. I can't say enough good things about them. The blades themselves are finally showing some wear after several years of hardish use (I end up floating a lot of small water and blade bashing).

I got to row a little with Coley's new SquareTops and I thought they were stiffer from my msx-g's and, personally, I didn't like them quite as much.

I have Cataracts for my pontoon boat with the floating blades. They are much stiffer (granted, they are also shorter) but feel REALLY burly. Those floating blades can take a hell of a beating too.
