Have you tried pushing the boat from the rear?
When I have used trax (which I don't do on my home lake, but I do on the beach in FL), I lift the bows, kick the trax under to the shouds, tie to the shouds with a bit of slack, lift the stern and go. The axle goes back a few inches, but the boat is generally balanced enough so that all my energy is directed forward.
It's kind of fun, if the wind is coming in from the water, to leave the sail up and "sail" it back up the beach at the end of the day.
When I've used trax with cradles, I've thought it takes more effort to line up and rotate the cradles, than the benefit they provide.
