Tom,

 

You have made a wise choice for yourself.  Make sure you didn't miss all the information.  The big tail creates a W & B consideration.  Lancair made an extended engine mount to help solve that problem.  If you do not have the longer engine mount, carefully consider where you locate items like the battery, hydraulic pump, etc.

 

 

Thanks for your reply.  I do not doubt the safety and handling qualities as you mentioned them in your original letter(archives) and again in your response to my question.
However, a few key words in your and other's responses standout because they have important meaning for my safety.  I am speaking of the comments regarding a pilot's skill and experience in relation to flying the original design stabilizer.  
  Being a low time pilot, I am trying to build my kit in a way that minimizes my exposure to stupid pilot errors, looking for any increase in safety margin I can grasp.  Since it appears there is no safety downside to flying with the larger horizontal stabilizer, I'll use the MKII.
  It appears that both styles are good enough. I appreciate everyones' comments and the experience on which the comments were based.
