    Did you really mean 99% CL?

    The Spergel et al limit using CMB, 2dFGRS power spectrum, and HST Key
    Project Hubble-constant limits is w < -0.78 at 95% CL. You should add
    a sentance to that effect and note that our constraints are as good and
    are complimentary in the sense that he do not use the Hubble constant
    or LSS constraints. (I think that is a very nice aspect to point out.)
    If we then add 2dFGRS, we can quote that separately in this context,
    but then us it in the abstract.

    Our w range is greater than Tonry et al, but our upper bound on w is
    better. We can see whether the reviewer makes us quote that, but for
    now leave it out.

    Also, I'll wait for Submission 2.
