Just after we got our Lancair 360, I felt that the doughnuts made it too
skittery (sp?).  It just wouldn't plant itself -- you were below flying
speed, but too light on the tires, and with low energy adsorbtion, you
just bounce along the runway.  I read the LML, looked at a Spry shock
installation and decided to go with the Sprys.  There was a vast
improvement in the skittery feeling.  
   They came preadjusted and slipped right on, but I had mismeasured
about 0.020" on length on one side, so had to readjust.  Other than
that, there was and has been no problem with them.
