Hey Harvey,
Welcome to the Hobie Forum. I have been using a Trailex trailer to haul my OB and Sport for over 3 years now, and it has worked great. However, there is a kind of art form to the tie down method that was taught to me by Andy, the guy who sold me both my yaks from the Wilderness Way here in Tallahassee some years ago.
First, forget the ratchet-type tie down straps. They can put enough pressure on your yak to actually deform or damage the hull unless you are careful. Use the pressure (spring-type) buckles as you see in the below post. It is important not only to use the Mirage Drive well and/or the scupper holes, but to also have some sort of fixed central attachment point, as well as a non-skid surface (you can use pool noodle halves attached with cable ties) on which to place the yak to prevent lateral movement. The fore and aft movement is no problem if you secure at least part of one strap thru the Mirage well, or a scupper hole. Also, IMHO, transporting yaks usually works best if they are cockpit down on the cross bar or trailer frame--less chance for slippage when you hit the inevitable bump on a two-lane or back country road. This, of course, assumes that you are NOT using saddles that are designed to support the hull itself when the boat is cockpit up. Good luck. Just my $.02 worth.
