Rick--check out the Maxima Hunter 350's (8.9gpi)--if you shaft length is around 28"--you'll be right in the ball park of the total arrow weight you're looking for.
With my set up, I'm using the GT Ultralight 400, 27.25", w/2"blazers, GT series nocksand 100g slick trick--groups plenty enough out to 40 yards.
