Having had my stint with aerobars, I used a Specialized ruby with great success in the bars. There is little padding but great gel in the seat area, and on the sides of the cutout. The cutout is very forgiving and the nose is so minimal is doesn't get in the way. Have you looked at the adamo saddles with no nose? I don't know if they have one with the width you need, but I know several tri folks that love it. I wanted to try one but never found one wide enough for me, I too am in the 155 club. SSM also makes an aspide glamour arrowhead K, with cutout, also liked that. Wore one out.
