Invoking the need of a panel indicates a fear of assuming a responsibility (i.e. diluting it into the faceless panel.) Why not just try it out, and afterwards evaluate? If it works, great; if it doesn't, if possible learn about why it didn't, and move on to the next strategy. All you'll lose is a year or two. And there is such thing as the right timing. In any case, nothing stops the legislator from doing both: going the panel way and the non-panel way simultaneously.
