One of the first Rocket kits I built was the Semroc Vega. Semroc includes a length of kevlar thread, and instructs the the builder to tie an overhand knot, and anchor the kevlar under the front of the engine hook, right where it goes into the motor mount tube. This seems like such a simple and effective method that I started copying it on all my low power builds. Other places I've checked, though usually recommend tying the kevlar around the motor tube, anchoring it to a centering ring:

Any problems with the Semroc method, or should I switch to knotting around the tube?
